So, I have a question for you ladies. My dd is 3. She is tall and thin. She is too tall for a 2T in pants. They come up really high and it looks like she is wearing Capri pants. In warmer weather that wouldn't be a big deal. Since it is cold out, I want her legs to be totally covered. When I put her in a 3T in pants, the length is always good. However, they are saggy around the waist. She is constantly tugging at her pants, and I try to help her keep them up.This is especially true when I want her to wear jeans or khakis. There are those stretchy cloth pants, and those work okay but they not very warm. I looked in Target for a belt, but I didn't see one that was small enough. I want something easy that she can undo herself so she can use the potty on her own. Any suggestions as to where to look? Thanks.
