2 month shots

Brianna

My 2 month old got his shots today and was fine afterwards, he ate and then went to sleep for a couple hours. He woke up screaming and spit up a ton and now won’t eat. He just fell back asleep but my question is, how long do these side effects last? I know I can give him Tylenol if it gets too bad but I’d like to know how long the fussiness and soreness usually stuck around. Thanks!
