That is what my little guy has. I went to 4 Dr's before discovering this. My gut kept telling me something wasn't right. Spent all day at clinics before finally getting referred to a specialist. After 2 Ultra sounds they finally discovered it. Anyone who has an infant with constant vomiting or spitting up should get it checked out. My first, second and third Dr told me this was normal. BS!! Its not. Anyways, he's going in for another Ultra sound tomorrow which will most likely result in a surgery to loosen or expand the lower stomach muscle. I'm still learning about this condition. For those interested here is a link.
