Re: At a loss... : /
Did he pass meconium in the first 24 hours? This is out of my league, but I think it's unusual for a 3 week old to not have a normal (unstimulated BM) for almost 2 weeks, especially if, as I understand it, he's now exclusively breast fed. I would definitely bring this up with his doctor -- there are conditions of the colon that can cause this problem, and I personally would want my child evaluated.
I say this because my DS who was born on the 20th didn't have a BM for almost 30 hours after birth, and we made this whole plan with a pediatric GI in case he continued not to poop. Turns out he is totally fine (he pooped almost immediately after the complex follow-up plan was made, suggesting that he does things on his own schedule) but we went through the list of possible problems that newborns not pooping can be, and it may be worth running a few tests. Maybe I'm getting riled up over nothing...other people can chime in.
