In between diaper sizes?

ya

So we’ve been using pampers since birth and my little string bean is officially too big for pampers newborn today (8 weeks) judging by the blowouts but we tried pampers size 1 and they leak so I tried huggies size 1 and low and behold they also leak. I’ve tried folding the diapers down but it’s just huge gaps between her butt and legs no matter what I do! What brand/size are best for this in between transition. I have changed her clothes like 4 times today already and I can’t let her be wet when she’s sleeping tonight ( she sleeps 6+ hours at a time).
