Infant tylenol

My son who is 4 months has strep. Also teething ive been giving him Tylenol as thats the onky thing that is soothing him. Ive given it too him as directed but maybe like 3 or 4 times a day. I just feel like thats alot and i feel like its doing to much or I feel bad for giving it too him. I dont why i feel like this
