my son still has not pooped unless I make him ! and everytime I fed him yesterday or any other day he spit up and not just normal spit up he covered his clothes, my clothes, and it came out his nose I'm starting to wonder if he has GRD he stays fussy to where I can't get nothing else done. I just pray god helps him feel better!!
