Leaky diaper

Recommendations on diapers that won’t leak overnight?? My son leaks through his diaper literally every night.. I have to set an alarm so I can change it twice so it won’t happen. He’s been in luvs, parents choice, and huggies.. would pampers possibly work? He goes to sleep with a bottle and very seldom will get 3oz of water in the middle of the night if he wakes up. We tried moving up to a size 6 and we make sure his pp is pointed downwards.
