Upper GI Test question

[widdletigger]

They are sending my son in to have an Upper GI done . . . They told me he will have to drink something. Now I am wondering, will whatever they make him drink stain my diapers when it comes out the other end?

Anyone have an exprence with this?

Also, if you can tell me some about the test (if your child has had it) Id appreciate it. his test is tuesday at John Hopkins Hospital. im kind of nervous. But we are kind of getting a bit more used to all these tests.
