Sleeping after vaccinations?!

Krystin
My daughter got her 2 month vaccines today (please spare me the anti vaccination replies please lol). She got the shots around 10:30am. I gave her Tylenol around 11pm and again at 4pm. She has LITERALLY been sleeping all day. She ate at 12 noon and then fell asleep and woke at 4 to eat again and went straight back to sleep. Is this normal after vaccines?!
