The most scary moment in my life

My baby has been dealing with excessive saliva and he chokes a lot. Not a day pass by that he doesn’t choke but I pad his back and quickly he starts to breath again. But yesterday he started choking and I started padding his back but he got worse. He started to turn red then blue. His eyes and mouth was wide open. I checked his breathing and he wasn’t breathing 😭. I started to panic but never stop CPR. I told my oldest daughter to call 911. Suddenly he stretched and got stiff like a plastic doll he was purple. Honestly by this time I thought my baby was dead so I walked into my room cause didn’t want my daughters to see him like that. I putted him again my chest and suddenly he started breathing again. Now am to scared of every little noise he makes and I can’t take away the image of him shocking. Paramedics arrived and confirmed that he was back to normal and i have an appointment tomorrow but I cannot have peace anymore. I never been so scared in life. I don’t sleep thinking that he might chocked at night and not able to help him if I am sleep.
