Baby fever

Mrs B

So my 4month old just got her 2nd dose of her shots yesterday . she always takes them well but she woke up today with a temp for the 1st time , doc did say that a fever was normal i temp check her & got 100.1 . Gave her a lil Tylenol , fed her & lots of cuddles . How long does the fever usually last ? Should I keep her blanket on her even though she’s hot ? Ik I should’ve asked doctor this but after being at her app for 2 hours past the time it was i physically tired and just wanted to monitor her shots and behavior + I always like to hear what other moms do .
