worried about 5-month old with gastro problems

[Guest guest]

I have an 8 yr old dx Aspergers. She had lactose intolerance that then grew

into gastro problems and eventually IgG to casein. Now I have a 5 month old

baby who spits up everytime she eats. I'm so worried that this is a

predisposition to gut problems later--and eventually a poor immune system. She

has received two vaccines, and my ped seems open to spreading them out. Does

anybody have any advice on the spitting up--is this is a reason to be concerned?
