I have also breast fed more than once and diaprbayb really describes breast milk accurately - thin (watery) body temperature warm and sweet. Breastfeeding is a WONDERFUL experience.
I was the oldest of 4 kids and REALLY wanted to be a baby again when I was about 11. I pinned myself into towel diapers, sqeezed into toddler plastic pants and actually had my first orgasm dressed this way and crawling on a bed.
If Mommy is a dietitian there is no danger to a babyfood diet. You will certainly have the nutrients you need - just watch sugars and make sure you are not getting adult sized doses of vitamins and minerals at baby levels. For example an excess of iron or vitamin A or D.
