Choked on spit up :(

Juanita

So my son is 5 months and was rocking back and forth on my lap, he does that when excited, and suddenly I heard him almost snorting like a pig and I looked at him and he was struggling to breathe and his eyes were watery. So I hit him on his back and he coughed and I layed him down and he just smiled at me, with watery eyes. It was so scary!! I always hear they cant actually choke and die of spit up but I was so scared. Now I have to go to work and leave him with dad and I'm panicking :( hes of course all smiley and laughing like nothing happened. Uuggghhhh
