Training pants - skinny

Pen • 8/17 🌈👧🏼 | 11/19 🌈👦🏼| 👨‍👩‍👧‍👦

My girl is skinny and kinda tall - 18-24M pants are the right length but too loose at the waist.

That said, we’re going to start potty training in a couple weeks and instead of buying more diapers I’d like to get training pants.

Can anyone speak to the fit of training pants for skinny tots?

We currently use seventh generation diapers and sometimes honest if our target doesn’t have seventh generation in stock. She’s in a size 4 seventh generation but the size 4 honest is too small.

Thanks!
