Maternal vaccines and breastfeeding

Did you know babies routinely get antibodies to anything you’ve been vaccinate against? Babies get temporary disease protection from you in this way. When you are vaccinated, your body has an immune response that makes antibodies to what you were vaccinated against. Antibodies are then secreted in breast milk to your baby. The type and quantity of these antibodies, and whether they provide any protection for baby after they are swallowed, are dependent on the vaccine received and maternal factors that influence immune system function such as genes, age and health.

Antibodies in breast milk have not been shown to reduce baby’s response to their own immunizations. However, some studies suggest that breast milk may improve baby’s immune response to some of the vaccines they receive.

If you do decide to be vaccinated while breastfeeding, there is no need to pump and dump your milk. Or to stop breastfeeding for any amount of time. When considering the vaccine, or any medication, most want to know whether a dangerous amount of a substance will be filtered into our milk and cause harm to our baby. For most drugs, so little gets to the baby that there’s really very little theoretical risk. Even if a drug or vaccine does end up in breastmilk, anything that goes through breastmilk also then has to go through baby’s gut before reaching baby’s bloodstream. The mRNA molecules in the Pfizer or Moderna vaccines, if they made it into your milk, would have to survive baby’s stomach acid first.

While breastfeeding, it is highly unlikely that an intact lipid from the vaccine would enter your blood stream and be passed directly into your milk. If it does, it is even less likely that either the intact nanoparticle or mRNA could be transferred into your milk. In the unlikely event that mRNA is present in your milk, it would first go through baby’s digestive system and would be unlikely to have any biological effects. The vaccine is supposed to trigger an immune response in your body. It helps your body recognize the virus when you’re exposed and fights the virus early, reducing the severity and length of illness. Once your immune system recognizes the SARS-CoV-2, the virus that causes Covid-19, antibodies are made to protect you and those antibodies may pass into the breastmilk. Researchers have already found Covid antibodies in the breastmilk of previously infected women, though they don’t know yet how much protection these antibodies give babies.

Choosing to be vaccinated is a personal risk/benefit decision to be made between you and your health care providers. If you do chose to be vaccinated with the COVID vaccines, there is no need to pump and dump for concerns of your milk harming your baby.

The Second Night

Second Night Syndrome : What absolutely every parent should be warned about in pregnancy.

Second night syndrome. I hate the word syndrome. It implies something is wrong. For nine months your baby has been in your belly. Heard your voice. Felt your body move. Listened to the rush of your blood flow past and heard the gurgle of food digesting. Their existence controlled by the cycles of your body. Then the intensity of labor and delivery propels them into a new world that sounds, smells, and moves differently. The sheer exertion of being born often makes babies as tired as their mothers. It is typical for babies to have a deep recovery sleep about 2 hours after birth (after their 1st breastfeed).

On the second night, however, most babies will want to frequently nurse. This helps with two transitions: meconium to soft, seedy yellow poops and colostrum to mature milk. This cluster feeding catches many parents by surprise and leaves them wondering if baby is starving. Unless baby is not latched well or efficiently feeding, this is normal and the cluster feeding will help transition your milk.

Many babies, though, don’t want to be put down during this process. Each time you put them on the breast they nurses for a little bit, go back to sleep and then cry when placed in the crib. A lot of moms are convinced it is because their milk isn’t “in” yet, and baby is starving. It isn’t that, baby’s awareness that the most comforting place is at the breast. It’s the closest to “home”. This is pretty universal among babies. When baby drifts off to sleep at the breast after a good feed, break the suction and take your nipple gently out of their mouth.

This is also protective of SIDS. You’re exhausted from labor and delivery and just want to sleep. But night time is when newborns are most vulnerable to respiratory complications and SIDS. By waking you frequently at night, you are waking frequently to check on the well being of your baby when they’re at their greatest risk of infant death. Waking regularly at night for the first few months to feed also helps babies from getting into too deep of a sleep state which can cause them to stop breathing. Instead of seeing the loss of sleep as a negative for you, consider the positive reason it has for baby.

Don’t try to burp baby, just snuggle baby until they fall into a deep sleep where they won’t be disturbed by being moved. Babies go into a light sleep state (REM) first, and then cycle in and out of REM and deep sleep about every ½ hour or so. If they start to root and act as though they want to go back to breast, that’s fine… this is their way of comforting. During deep sleep, baby’s breathing is very quiet and regular, and there is no movement beneath the eyelids. That is the time to put them down.

Second night syndrome. As described above, when all is going well it is normal for baby’s to cluster feed on the second night to help milk transition and poop out meconium. Some babies do not efficiently feed, though, and intervention may be necessary.

🩺Medical interventions and pain relief during labor and delivery, maternal health complications like PCOS, uncontrolled diabetes or hypothyroidism, or large blood loss during delivery may delay the transition of your milk.

🧸If your baby not latched well, has a tongue tie, or hasn’t figured out how to coordinate sucking to actually transfer milk from the breast, intervention may also be necessary.

🖐🏽The first line of defense is hand expressing your milk frequently. Hands are better at expressing colostrum than a pump, although a pump is a great way to stimulate milk to be made.

🥄Dripping your milk into baby’s mouth from a spoon or small syringe can help jump start the feeding process.

❓If you have any doubt about either your milk supply or your baby’s ability to breastfeed well, reach out to a qualified IBCLC ASAP to get to the root issue and get you back on track.

♥️There is no shame in supplementing your baby if needed during this time of learning. Remember, you can always use your milk first by using your hands or a pump if baby hasn’t figured it out yet.

If Goldilocks Needed a Breast Pump

IF GOLDILOCKS PUMPED

What pump do you have? What size flange are you using? The answer can make a huge difference in pumping success.

Not all pumps are created equal. Prior to the ACA, there were few pump choices. Once laws said people needed to be provided with a breast pump, and insurance would fit the bill, lots of companies flooded the market with pumps. Not all of them are good, and some will even sabotage your supply. You want a pump with a good motor in it that has lots of variability in the cycle (how fast or slow it pumps) and suction (how strong it sucks).

You also need to be mindful of the flange you’re pumping on. Most companies will send a standard 24mm flange. Sometimes they’ll send a larger size as well. In reality nipples, and thus flanges, are not one size fits all. And in my practice I hardly EVER use the 24 or bigger flanges. For almost all of my families we’re sizing down. Some times significantly smaller.

Flanges are the horn shaped part that actually touch the breast. The fit of the flange can make or break your pumping experience. Too small and friction can cause pain and even damage (and pain makes it difficult for milk to let down). Too large and the breast may not be stimulated well, which inhibits your let down to have milk flow. When too much areola is pulled into the flange, the tissue swells around the nipple pores and can prevent milk from efficiently emptying from the breast, resulting in plugged ducts, pain, tissue breakdown, and eventually a reduced milk supply. Using too large of a flange from the beginning may even prevent you from bringing in a full milk supply. Do you ever pump for 20+ minutes and still feel like there’s milk in there? Most likely too large of a flange. The stimulation from the pump is triggering you to make more milk, but the size of the flange is preventing you from emptying that milk efficiently. Poor flange fit can also impact the suction of your pump and how well it functions with your body. If you have the suction all the way to the highest level and aren’t emptying well, you flange is too big.

Flange fit tips:

Some of the flanges I tried

🗝Flange fit isn’t based on your breast or areola size, it is JUST the size of the nipple and how it changes with suction. Some nipples are dense and don’t stretch much. Some are super elastic and swell a lot. How your nipple responds to suction can make a difference in which flange you select and if other products are needed to happy pump

🗝Proper fit isn’t as simple as measuring your nipple, but it’s a start. See a trained IBCLC to help if you haven’t found the right fit or are struggling with poor output, pain/damage, or plugged ducts

🗝A small amount of space around your nipple in the flange tunnel is good. There should be no space around the areola or in the larger bell part of the flange. If your breast tissue recoils back into the horn part of the flange with every cycle, the flange is too large. If the tissue is white where the tunnel meets the horn, the flange is too small

🗝Pain or blanching means it’s the wrong size

🗝Nipples rubbing against the sides of the flange tunnel mean fit needs to be improved and there is a risk of pain and damage

🗝There should only be a small amount of areola pulled in the flange tunnel space. The bell or horn part will have most of the areola held back so it doesn’t get pulled into the tunnel

🗝The nipple tip shouldn’t hit the back of the flange. This means you have an elastic nipple. Sizing up isn’t necessarily the right answer. Using a pump insert, cushion like @beaugenmom or @pumpinpalofficial may be a better solution

🗝Evaluate as you pump. You can changing flange size mid-pump to improve comfort if you’re between sizes. You may also need to change the flange size the longer you pump. Our nipples can become more elastic and larger or smaller with time.

🗝Every nipple is unique and each side may use a different size (or shape/brand!). There are all kinds of flange sizes, inserts, and cushions to improve the pump experience

How often should I breastfeed or pump?

BREAST STORAGE CAPACITY

The size of your breast has nothing to do with the amount of milk you will make. The size of your breast is determined by the amount of fatty tissue in the breast. The amount of milk you will make is determined by the amount of glandular tissue in the breast that makes milk. This glandular tissue starts growing during puberty. It increases during pregnancy and is part of what accounts for the increase in breast size during pregnancy. Everyone’s storage capacity is different.. just like every breast size is different. However breast size does NOT equal breast storage.

Small capacity: Approx 2-3 ounces per feeding/pump. Baby may need frequent feedings: 10-12 per day. Baby usually takes both breasts and may want each breast twice. Parent feels uncomfortable quickly between feedings and sees a supply drop with more than 3-4 hours between feedings

Medium capacity: Approx 3-4 oz per feeding/pump. Baby may feed 8+ times per day. Baby may take one breast or both breasts each feeding. Parent feels uncomfortable and see a supply drop with more than 4-5 hours between feedings

Large capacity: Approx 4-6 oz per feeding/pump. Baby may feed 6+ times per day. Baby may only take one breast per feeding. Parent may go up to 6 hours without seeing a drop in supply

XLarge capacity: 8+ oz per feeding/pump. Baby may feed 6+ times per day. Baby may only take one breast and parent may still feel full in that breast. Some babies may be gassy from higher foremilk intake as they may not drain the breast fully. Parent may go 6+ hours without seeing a supply drop. Parent may still feel uncomfortable between feedings depending on how quickly the milk fills the breast

All capacities have the same ability to feed baby well as long as the breast is routinely being emptied.

Do I need a breast milk stash?

NO STASH NEEDED

If breastfeeding is going well and you’re planning on being home with your baby or only gone for a few hours at a time there is no need to have a huge freezer stash. Having milk in the freezer is a nice security, especially is your have to work or will be away from your baby. But if you’re always with your baby or are only gone for a short while, there is no need to have a stash.

Having the right stash for your family means having enough stashed for when you’re away from your baby. If you’re gone for one feeding, you only need one feeding worth of milk. If you’re gone 2-3 feedings, you need 2-3 feedings worth of milk. If your baby is being bottle feeding while you’re away, you would pump while you’re gone to tell your body the milk is needed. That milk then becomes the stash for the next time that you’re gone.

If you want to have a big stash, great!!! You can absolutely have that as an option. Just don’t feel pressured from other people’s journeys on social media to have something you may not need or use. I’ve had several moms who spent countless hours pumping and stashing only to have to donate or throw out the milk stash because they never used it and it was going to expire. I’ve also had several moms who thought you had to have a stash and were relieved to know they didn’t! Do what is best for you and your baby and not based off of anyone else.

You’ve got this. Trust your body. Trust your baby.

My baby’s weight gain is slowing

WEIGHT GAIN

While your young baby is supposed to gain on average an ounce a day (30gm), weight gain slows as baby ages. From 4-6 months babies should only gain 3-4 ounces per week (90-120gm) and from 6-12 months babies should only gain 1-2 ounces per week (30-60gm). If you have been tracking baby’s weight gain and see the scale slowing down, don’t be alarmed if your baby is older. Continue to watch for lots of wet diapers and consistent pooping. Trust your baby and trust your body.

Where has my breast milk gone?

Some times we can sabotage our own milk supply from little things that we don’t understand will make a difference. Here are the top ways to accidentally drop your milk supply:

😳Putting baby on a feeding schedule in the first 3-4 months

😳Watching the clock instead of feeding baby on demand

😳Sleep training in the first 3-4 months after birth

😳Waiting for your breasts/chest to feel full to pump or feed

😳Not pumping when baby is getting a bottle

😳Letting partner feed a bottle in the middle of the night to get more sleep (and not getting up to pump)

😳”Topping off baby” after feeding, especially during the witching hour phase. (I’m not talking about when supplementing is necessary or if you’re on a triple feeding plan because of true low supply or baby weight gain. Supplementing after breastfeeding can be needed, but you would also be pumping at that time)

😳 Not pumping enough when returning to work

😳Using the wrong size pump flanges

😳Using a poor quality pump (insurance companies have to provide you with one, but that doesn’t mean they’ll give you one of quality)

😳Going back on hormonal birth control at your 6 week postpartum checkup

😳Taking nasal decongestants or allergy medications

While these seem like normal recommendations from many parent groups or even your health care providers, these subtle things can sabotage milk supply. Your body works on a demand and supply basis. The more you empty or demand from the breast/chest, the more milk it will make. Want to increase supply? Increase the number of milk removals, give young infants free access to feed on demand, and watch out for medications, hormones, of pumping traps that can sabotage your success.

Vitamin D supplements and breast milk

VITAMIN D

Were you told by your pediatrician to give your baby vitamin D drops? Vitamin D is absolutely critical strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease where the bone tissue doesn’t mineralize properly, leading to soft bones and skeletal deformities. Recent research also tells us that vitamin D is key in maintaining our immune systems for regulating both infection and inflammatory pathways. If you shun the sun, have a milk allergy, or follow a strict vegan diet, you may be at risk for vitamin D deficiency. Known as the sunshine vitamin, vitamin D is produced by the body in response to skin being exposed to sunlight. It is also occurs naturally in a few foods like certain fish, fish liver oils, egg yolks, and fortified dairy and grain products.

Our bodies are designed to make very large amounts of vitamin D through exposure to the sun (10,000—20,000 IU in 24 hours, after 15—20 minutes of summer-sun exposure in a bathing suit/45—60 minutes of exposure for those with darker skin tones). However, in an effort to decrease our risk of skin cancer from over exposure to the sun, we’ve limited our ability to keep our vitamin D status at a normal level from absorbing it directly from the best source. That said, those living where clouds often cover the sky or in cities with polluted air quality will have a hard time getting sun exposure for natural vitamin D. People with darker skin tones are more likely to have low levels of vitamin D, as well, due to the increased pigment in their skin. They require nearly four times the length of sun exposure in order to penetrate the skin to manufacture vitamin D.

Vitamin D is essential for babies. Your pediatrician cannot tell you to put your baby in the sun, even though that is the best source of vitamin D, because of the risks of skin cancer. So they should have advised you to give your baby 400 IU of vitamin D each day, usually given by drops in the mouth.

All formulas sold in the United States have at least 400 IU/L of vitamin D; so if your baby is drinking 32 ounces of formula, vitamin D supplementation is not needed.

But what about from breast milk? Human milk is a very poor source of vitamin D, usually containing less than 50 IU per quart. This is why the AAP recommends all breastfed infants be supplemented. This does not mean there is anything wrong with the milk, but an issue in the recommended amount of vitamin D the lactating parent should be taking. This goes back to the sunlight recommendation. If you were getting 15-45 minutes of sunlight (depending on how dark your skin tone is) 3-4 times per week, your body would have plenty of natural vitamin D to pass through your milk to your baby. Many who live in the US either don’t live in a location where that’s possible year round (hi, Chicago in January) or maybe can’t get out in the sun because of needing to work. The Academy of Breastfeeding Medicine (a global organisation) recommends that “The breastfeeding infant should receive vitamin D supplementation for a year, beginning shortly after birth in doses of 10–20 lg/day (400–800 IU/day) (LOE IB). This supplement should be cholecalciferol, vitamin D3, because of superior absorption unless a vegetable source such as ergocaliferol vitamin D2, is desired. … Vitamin D also may be delivered adequately through human milk.” Research has shown that as long as you as the lactating parent is taking 6,400 IU of vitamin D daily, there is no need to supplement the baby as your milk will have adequate amounts.

IUDs and Breast Milk Supply

Where did my breast milk go?

BIRTH CONTROL AND MILK SUPPLY

An IUD is a form of birth control that’s put into your uterus to prevent pregnancy. One of the most common forms of birth control, it’s long-term, reversible, and considered one of the most effective birth control methods. Many doctors will encourage new mothers to have them placed between 4-6 weeks postpartum checkup to prevent pregnancies too close together. The Paragard IUD is wrapped in copper and doesn’t have hormones. The Mirena, Kyleena, Liletta, and Skyla IUDs use the hormone progestin to prevent pregnancy. Be aware that each IUD has a different amount of progestin. They are not created equal. Progestin is also the hormone found in the mini pill.

Hormonal IUDs and the mini pill are often recommended by doctors as the best form of birth control for breastfeeding mothers because most of the research that is available says that they don’t impact breast milk supply. And many who use these methods don’t experience any drop in supply. For some, though, both the mini pill and the hormonal IUDs will drop breast milk supply, some times drastically. Every body is sensitive to different levels of hormones. If you have an IUD placed and notice a drop in supply, the only way to increase supply again is to remove the IUD. Increased pumping or herbal supplements will usually not be enough to increase supply again because you’re working against hormones. The only way to rebound supply would be to remove the IUD. If you’re considering a hormonal based IUD and aren’t sure if your supply will drop, consider taking a few rounds of the mini pill (progestin only) which is the same hormone as the IUD. If your supply drops, you only have to stop taking the pill and your supply will rebound much quicker.

Did you use a hormone based birth control? Did you notice a change in your breast milk supply?

Breast milk supply drop at six months

SIX MONTH DROP

For the first six months after birth, baby is supposed to be on an exclusive breast milk diet. At six months and beyond your breast milk goes through a major change. The volume of milk slowly drops because baby is eating and drinking other foods. They may also be sleeping longer at night and are more active during the day. Your milk is super smart and shifts with this drop to have more antibodies and a higher fat content. The breast makes milk based on how it is emptied and what your hormones are doing based on how old baby is. Your hormones are also shifting and you may start your monthly cycle again. Many experience a further dip in supply around the time with their period. If you’re exclusively breastfeeding, you may notice baby pulling or tugging on your nipple or using their hands to beat your chest while feeding. If you’re pumping, you may slowly start to see less milk each pump session. Usually months 5-7 are the hardest from a baby behavior perspective and it settles out again as baby eats more table food and your hormones adjust. If breastfeeding is your goal, just keep offering the breast and pumping often.
