Dear paps,
depending on where you live (as if it's hot and dry in the house) the baby might get dehydrated quickly, you would have dry diapers (no pee-pee) as a sign. I can't remember by when the soft spot on the baby's head closes, but if he still has one it would dent in. Water is the best solution (esp. if there is no more vomiting) to help fight off whatever bug he got. I'll say a prayer for him tonight also
