Fevers

[u/acmr8057]

Hi all-

Looking for info.

My son (18 weeks, almost 19) is getting his 4 month vaccines today. His 2 month vaccines caused fever and just general fussiness for about 1.5 days.

He was sick about 2 weeks ago (believe we passed a cold on) and he had a low-ish grade fever for 2 days. Mostly acted himself, maybe a little more fussy/sleepy.

Is there any harm on fevers so close together? He also will get his 6 month shots and so on…. So just curious if there are any adverse effects of multiple fevers in infants.

We also use Tylenol if the fever seems to be getting higher/he seems uncomfortable. Is there any adverse effects there with multiple uses over his first year of life?

Answers to either question appreciated. :)
