Choking baby!

Butterfly
My baby boy is one week old today.! What a week to celebrate my first baby.! However, today we had a scare he was lying in his bassinet when I noticed his face was beet red, I lifted him up and milk came gushing from his nose and mouth.! He was choking!! It scared the life out of me and suctioned his nose and throat for dear life as he gasped for air. Now I'm needless to say terrified to fall asleep and it happen again for some reason. Please glow mommies tell me how to get some sleep and a lil peace from this incident today. I feel like I shouldn't sleep and I should watch him all night and I hate my husband as he lies next to me snoring his life away!!! Please help..
