Hello MAMAS SOS I'm in panic!!! We're on the GIV the baby ate and everything he ate came up through his mouth and nose, and he keeps asking for more to eat, should we give or not??? I was scared, it's been quite some time since the last feeding, but when I fed him he would squirm his legs and poop, maybe because of that ? We've been at this for 3 weeks. The doctor will come tomorrow, I'm worried so much, could anyone share their experience!!!!
