Some times even the best lactation consultants and feeding therapists can miss a posterior tongue tie in the immediate days or weeks after birth. Having a frenulum under the tongue doesn’t automatically mean it’s tied. A long, stretchy frenulum that allows full movement of the tongue is normal and not something that needs released. However, sometimes a frenulum can allow the front of the tongue to do what it needs to, but still be tied at the back. These are what I can tricky posterior ties. Mom may have lots of milk and baby transfers well from the breast in the early days or weeks post delivery. Mom may have no nipple pain or damage whatsoever. Only they come back a month later with new symptoms like slow weight gain or feeling like there breast isn’t emptying. Why is that?

Mom’s body often compensates well during the early weeks post delivery. The uterus doesn’t tell the breasts how many babies came out. So her body goes into overdrive to make more milk than needed from the start. As time moves on, the body figures out how much milk to make and drops supply to just what is being emptied. A baby that rode on mom’s robust post delivery flow may all of a sudden start to struggle at the breast as supply regulates. Based on how the anatomy is, there may never have been nipple pain or damage. If the baby has a high palate where the front of the tongue can still move well and mom has a large nipple that fills baby’s mouth well, the nipple may come out creased or pinched, but without pain. The anatomy on one or both sides masked the tie while baby was small. 

If breastfeeding was going well in the beginning, but symptoms start to pop up later, working with a qualified lactation consultant can help figure out what’s going on. And some times that means finding a posterior tie that was originally missed where a release is necessary to get feeding back on track.
