Please can anyone help me, bubba's outgrown her size 1s and I'm really struggling with the size 2s. She's really slim but has chunky little thighs so all her nappies are a bit loose around the waist but digging into her little legs

Have so far tried bg v3 (I think...) green kids pockets, coolababy pockets and some old bambinex. The bambinex and her size 1 bamboo tots bots were perfect while they fitted but the size 1 tots are too short on the rise now and the size 2 bambi are too slim. At last measurement she had 16" waist and 9 1/2" thigh
