Diapers leaking overnight 🙄😩

So my son is 15 months old and has pretty much always been a good sleeper sleeps through the night even with a super soggy diaper he’s always been a pisser lol like he pees A LOT which I guess is okay but I can’t keep him dry in the night even if I do go and change it in the middle of the night he wakes ups legs soaked bed smelling like pee sometimes even the bottom of his shirt will be soaked. I’ve been using the huggies overnights for about two months first they worked great like no leaks at all I thought the problem was solved then the past two-three weeks he’s leaked through them bad too like the diapers have been exploding which really makes me angry I don’t want that stuff on my baby. Any other diaper suggestions anything??? Also been thinking of introducing the potty since he apparently can’t keep his clothes on lol
