diaper help

need help, my daughter is gonna be 2 tomorrow and wears a size 6 in diapers. I've tried potting training her but shes just not ready. I've tried huggie movers and pamper cruisers but when she wakes up the next morning she has peed through them even during the day. I have no idea what other diapers to try, I have tried huggies snug and dry and they're terrible. like the size 6 fits her belly good, but around her legs they're loose but size 5 don't fit her belly. thanks for yalls opinions and advice.
