Ask your pediatrician first before u give any medicine , depends what heyre sick with how much they weigh, and how much they'll need if they need medicine... I would strongly advise not to administer both because they're are a drowsy medication... even tho ur baby is five months their livers are still very tiny and sensitive and too much medicine can harm than do good

I wouldn't suggest that since Tylenol and Benadryl has the same ingredients

Yes it will keep his fever down and help him sleep
