S.A.
I'm a pharmacist who's 3 month old daughter recently had her first cold (from daycare too). I just wanted to respond regarding some of the information people have been posting about infant Tylenol. Tylenol is one of the most benign medications there is. You cannot build up a tolerance to it and it has very few side effects when dosed properly. I would stick to infant Tylenol before moving on to infant Motrin which could have a few more side effects such as stomach irritation (which you certainly want to avoid in a little one). A temp of 99 is perfectly normal in an infant so I would give her any medication unless she seems to be in pain, or her temp is above 100.4 rectally or 99.5 orally. The vaporizer will probably have the most obvious effect of helping her breathe. I hope this helps. Don't be afraid to give her Tylenol, but only if she really needs it for pain or an actual fever.
