Baby Choking in sleep

Does anyone’s newborn choke/gag while sleeping? I’m just curious if this is normal. I’m definitely going to bring up to doctor on his next visit. But I’ve notice he does it quite often, not every night but he will gag in the middle of sleeping then he will continue sleeping (he is still breathing after the gag) Also chokes a lot when breastfeeding. Any advice appreciated, Please note that he does have an appointment coming up on Monday and I plan on mentioning to the Pediatrician. Just wanna see if I’m just nuts for even mentioning it
