I started working for TDCJ a week after my first daughter/child was born. They taught us a lot of first aid and CPR. They told us they didn't give two shits if we ever used it on a convict, but we'd better take it seriously because it could save a loved one. They even taught child and infant CPR to us. I never forgot that training. I used it on my first daughter. She had just started solid foods(not pureed) and got something lodged, I can't even remember what it was. She was losing it quick. I yanked her out of her high chair, placed her body along my inner forearm with her face in my palm and started giving her shots to the back, just like I was trained. It worked. She blew whatever it was out into my palm and started crying. I didn't need to do CPR, but I stayed calm and acted. Get the training.
ETA: I just recertified since I took over as the intramural coordinator at the middle school where I work. I feel comfortable knowing that I at least know what to do if I need to do it. Hopefully, should I ever actually need it, I don't freeze.
