Sleep deprived mother 😭

I am definitely in need of advice. Does anybody else have a baby that spits up alot and you fear they will choke on it at night when you both are sleeping? My husband constantly gets woken up by me to check the baby just to make sure he's okay. I can't do much since I just had a C-section. But other than constantly bothering him to check the baby right next to us I lay awake because I'm to scared to sleep. At the hospital he did choke a couple times untill I was able to grab him and help. The nurses wouldn't believe me since I had all the nurses in training. Any advice would help.
