My son is 3, was born with a large omphalocele which only has skin closure at this point, no muscle. He came home from school yesterday at 1pm CST due to vomitting. He hasn t been able to keep much down. He recently went through a growth spurt, which with the way he was put back together for closure is a concern. We always worry about obstructions. We are going on 30 hours, he still Hasler diapers but we tried milk too soon so he has not kept much down. No fever or cramping,crying just tired. Can a growth spurt do this?
