Natural weaning is the biological process of gradually decreasing milk supply as baby gets older. This process starts around 7-9 months as baby takes more solid foods and progresses toward sleeping longer stretches at night. It ends when baby finally weans (which may not be until 2-3 years old!!). Natural weaning doesn’t mean that you need to wean baby from the breast. Decreasing milk supply doesn’t mean you’re at risk of losing your supply, either. Your breast is designed to match the stage of development your baby is in.
Milk supply iss highest from month 1-6 when baby is going through multiple growth spurts. They need to double their birth weight by 6 months. Milk is also the only food in their diet. Therefore, your milk supply is supposed to be at its highest to meet their nutritional needs. From 6-12 months, weight gain slows but their need for milk volume needs remain stable. It is natural as baby transitions from a full milk diet to a milk+solids diet to then a solids+milk diet that breast milk supply will shift along with it. Your milk supply varies compared to baby’s solids intake and there is a wide range of normal based on your individual baby. Some babies love solids and eat them in large quantities many times a day. Other babies continue on a mostly milk diet until almost 1 year. At 12 months, milk finally takes a back seat to solids, but still fills in nutritional gaps and acts like medicine against illness. From 12 months on there continues to be a wide range of normal for milk supply depending on your child’s eating and feeding habits. Some babies continue to nurse occasionally over night while others seem to become boob barnacles again and would happily stay on the breast all day, every day.
So what does this mean? If you’re exclusively breastfeeding you may not notice anything. You can continue to bring baby to breast for as long and often as baby wants. You may notice baby spacing out feedings or not nursing as long. They may want the breast more when teething or going through growth spurts or developmental leaps. They have days with little interest in the breast.
Moms who pump (either exclusively or because of work) report overflowing milk in the early weeks, often able to pump 4-6 or even 8-10 ounces in a morning pump session. By 4 months supply regulates and mom gets about 3-5 ounces per pump in place of a feeding. By 9 or 10 months it can feel like your trying to wring out a wet rag to get even 2-4 ounces a pump session. As long as baby has unrestricted access to the breast when your not working and you still have a regular pump routine in place no intervention is usually needed. Every journey is supposed to look different because it is your unique journey.
