I know that breast milk changes as a baby grows, and I think this isamazing. I am one of those people that likes to know how things work, so...
1. What exactly is different between milk produced for a newborn, and milk produced for an older baby?
2. How does your body know how to make the milk just right? Is it a hormonal thing? Does it just have to do with time elapsed since childbirth, or are there other factors?
Thanks, breasfeeding experts !!
