2 month shots question, now what???

Hi all, FTM here and traumatized after my baby girls shots today. She did okay until like 2 hours after, she woke up screaming. No fever, her shot areas must have been sore. So I gave her Tylenol and she did great for the next 4 hours. We gave it to her again just to be sure she was okay.

So now what do we do? If in 4 hours she’s not seeming upset or in pain do we still give it to her just in case? I cannot handle her screaming like that again it was the worst 30 mins of my life so far and not even exaggerating 😭

Any other tips to help keep her calm besides meds? And one last question! How long did it take your baby to seem like he or she was “back to normal”?
