Little B has had a cold for the past few days, and last night had his first loose bowel movement. He's been up since 7 and I've already changed two nasty dirty diapers.
The only thing different in his diet is that apparently while I was gone, daddy tried to feed him "go-gurt". Why daddy would do that is beyond me!

Anyway, how long with diarrhea before I should get worried/take him to the Ped?

Do you think it was the go gurt? Or part of his illness?
