Is it normal for a baby to be taken off FF & Solid foods when bub has virus?

is important to follow the doctor's advice. You aren't going to keep him off solids forever, and actually if he is tolerating solid foods (By this I mean that he isn't vomiting everything up) then you can start giving them to him again. When a child is vomiting and has diarrhea the biggest worry is dehydration. Make sure he's drinking plenty of fluids, and if he still can't keep anything down after 24 hours then take him to an urgent care center or to the emergency room for IV fluids.
