He's so annoying sometimes

I had my daughter through c-section. After they had numbed my whole body I got really scared obviously cause I have never been numbed before or had any surgery's, so I cried a little. My SO always thinks it's funny , and laughs about it. It upsets me because to me it was a very serious moment. Being numb and my whole body feeling so hot really really scared me. I tell him it's not funny and he laughs alittle then stops. It's so annoying to the point where if he continues he's not going to be in the room next time I have baby #2.
