My twin boys were born 8/28 at 30 weeks. Twin A (Vincent) has had multiple BM's. He is a little bigger than Baby B (Dominic) and has had an easier time. Dominic has not had a BM yet and it's been 96 hours (4 days). He also has greenish stuff in his belly (bile, most likely). So far all his X-rays, measurements, everything have been great. No sign of blockage or infection. But I'm freaking worried! I'm hoping to catch the docs on their rounds tomorrow. Any one have experience with their preemie not pooping for a few days after delivery? What was the result?
