Have you ever popped your child in the mouth or covered there mouths while throwing a nonstoo tantrum?

First off, i feel like the worse mother ever. My 2 1/2 yr old decided he would cry for at least 45min straight. Screaming etc. So naturally i covered his mouth and would pop him in the mouth to make it stop. It was noway near hard but i still feel bad. Im sure ill get ALOT of negative commennts as well. He wanted to go out in the heat of the day, as im 16weeks prego with #2 and get hot and dizzy and sometimes black out. So i told him wed go out later and he decided to throw a fit.
