Baby’s digestive system lays dormant in utero and they don’t p**p. Meconium is that thick, tarry first p**p that builds in the gut and colostrum is a high protein milk that acts as a laxative to p**p this out after birth. When babies are born they p**p a lot, even over night. The digestive system is waking up and maturing. The contents of colostrum and transitional milk aid in this process. Transitional milk includes high levels of fat, lactose, and water-soluble vitamins and is different in nutrient composition than mature milk. It contains more calories than colostrum. Around 2 weeks your milk transitions to mature milk, which has a higher water content than transitional milk, and there is a steady increase in the volume of your milk. As your body and baby adjusts to this change, your baby will eventually stop p**ping overnight: usually around 3-5 weeks. Some will still p**p overnight for longer than that (some times months) and that is also normal! Our digestive system wants to rest at night. Even as adults we typically don’t p**p overnight. Your body is very smart. It makes a higher water content, higher volume milk first thing in the morning to help baby have their first p**p of the day since their system has rested over night. It’s like their morning coffee. In the evening, your milk volume drops and increases in fat to help baby sleep and digest for growth and NOT to p**p. Diaper companies are aware of this change, hence the 12 hour leak protection diapers. Your milk and your baby are going through many changes. Trust your body. Trust your baby.
