In between sizes

My baby is in between newborn and size 1 diapers right now and I don’t know what to do. Newborns are too tight around her legs but 1’s are just too long for her body. She’s about 10 lbs now. She keeps having blowouts in both sizes because neither fit her properly (not because the amount of poop but the actual fit of the diaper). I’m kind of lost on what’s best to do for her.

Edit: we were using pampers but today i tried Huggies size 1 and it fits her much better! Seems it was just the brand. Still big around her waist a bit, but much better overall. Thank you for the advice!
