Nighttime Potty Training

My son turned 2 in May, and is fully potty trained during the day. He still wakes up with a wet diaper in the morning. I’m thinking of trying to ditch the night time diapers, but I am SO nervous 😕 I’m worried he’s not able to hold it during sleep yet, but he will only pee during naptime if he has a diaper on. As long as he is in underwear, he stays dry. He always tell us if he has to pee/poop and can pull down his pants and underwear, but can’t pull them back up himself yet.

Does anyone have any tips on night training? Any experience?
