Shots... please help!!!!!

My LO had his first shots about 24 hours ago. He hasn’t slept as much as he usually does... probably half of the sleep he would normally get in that time span. He falls asleep but will wake up within a minute or 2 crying. Once I pick him up or let him comfort feed he’s okay again. It’s like I can’t leave his side while he’s asleep. I’ve read many posts from other moms who said their babies just slept.

At this point trying to make a snack or throw in some laundry is impossible without him screaming. Prior to his shots he was pretty good now it’s as if he’s traumatized. What can I do? Just accept that he wants me at all times? In hopes he will feel better soon? I’ve given him tylenol every 4 hours. Last night he slept in our bed. Within the past 24 hours he’s probably slept about 8-9 hours.
