my son got his 6 month shots and has been fussy all night any suggestions?

I would still give him some Tylenol it helps with the soreness. My daughter had the same thing when she got her 4 mo shots

no fever a little warm though

Does he have a fever? Try to comfort him, give him a bath maybe. If he has a fever you can give him infants Tylenol. Just call your dr's office for the dosing instructions
