"First shots"

My son is getting shots tomorrow. Everyone considered them his first shots for some reason although he's gotten his hep b vaccine and blood taken at hospital when he was born. Anyways, my boyfriend and everyone else seem to think it's scary and that we are going to cry. But I'm so nonchalant about it that it's making me wonder if I'm the only one. I'm sure he'll cry but to me it seems silly to worry about it. It's a shot not his first boo boo lol idk
Am I weird for feeling this way?
