What are some good overnight diapers? - Parentberries

Our 15 month old has been wetting through his size 4 pampers swaddlers at night a lot lately. He’s only 22 lbs and the minimum weight on the size 5 is 27 lbs so it seems he’s too skinny to go up a size. [name_f]Do[/name_f] any of you have recommendations for very absorbent overnight diapers? (We are in the US)
Thank you!
