Hi Andrea, thanks so much for answering my posting so soon. I am just beside myself with fear. Yes my sons first poop 24 hours after birth was very hard, black stool...he screamed so badly. He has been constipated since birth, horribly so and has alot of blood, bright red fisher blood....doctors say it is normal with constipation and I should not consern myself with it!!! We give him lactulose, mineral oil, colase and senicot. He still never poops on his own or with anything but constipation. His poop is pasty yellow, mixed with blood. He does not eat much at all but drinks many bottles. Bottles are all he will take and I think he has a very strong milk appetite, about 7- 8 , 80z bottles in a day.Doctors think I need to deny the milk and see if he will eat solid food and I have done this for about 10 hours but I can't stand to do it any longer...he screams so badly...he will take water in stead but will not eat solid food.My doctor now says that CF babies are diarrea predomonant...???help.
