Pull Ups Sizing

M

Hi all! Is there a size larger Pull Up (or like brand) that’s a 5-6T? My niece is 38 lbs and the 4-5T is so dang snug on her poor booty that mama is having a hard time at night keeping them on. She’s only just turned 2 and is in no way ready for potty training developmentally. The pulls ups say they fit to 50 lbs but wooo weee is it snug on her peach 🍑. Thanks!
