I didn't nurse until late into the pregnancies though (3 mos into 2nd preg., 5 mos into 3rd preg), so I've wondered if my milk would have reverted to colostrum if I had continued or if my new baby would have missed out on that and started with the mature milk. I've also wondered if my milk had stayed milk had I kept nursing, would that be a problem for the new baby, not having had the colostrum, as in does colostrum serve as a sort of a primer in addition to all it's known benefits?<<< I nursed throughout my second pregnancy and then "tandem nursed" for approx 7 weeks. My second pregnancy was identical to my first in terms of weight gain (50 lbs!), birth weight of baby (10 lbs), length of gestation (42+ weeks), etc. I was unable to express any milk after about 18 weeks gestation. At that point, I encouraged less nursing and my toddler (18 mos when I got pregnant) reduced the number of times he was nursing until he was nursing only once or twice a day when I was at term. I had terribly sore nipples throughout and I felt that "antsy", annoyed feeling when he'd nurse but I continued because nursing was important to him and me. I did have colostrum at term. After birth, my milk was in by 48 hours (homebirth, newborn nursing "all the time"). My new baby regained his birth weight by 9 days of age, a 12 oz weight gain in 7 days. That's my story, FWIW... :-) Kathleen Salisbury ([log in to unmask]) LLL of Gig Harbor and LLL of Port Orchard (WA, USA) James (2-25-95) and Reed (6-9-97) ****************************************************************
