Best undies for your toddler

So my daughter is 3 years old and we can’t seem to find comfortable undies! She’s constantly pulling and adjusting herself saying she has a wedgie.

I watch her adjust herself and she’s pulling her undies, not itching/touching her privates. I’ve checked down there and it’s clean, there’s no rash or redness so I don’t think it’s anything like a rash or infection.

She just seems so uncomfortable. It’s like she doesn’t want her undies to touch her. she’s always pulling the part that touched her vagina down. She doesn’t even want to sit in her car seat because she complains about a wedgie! We’ve tried all types of undies and can’t find anything that is comfortable for her! Short undies, bigger sizes, smaller sized, bathing suit bottoms, different material… nothing works!

Anyone have any tips or undies they recommend???

A lot of you are saying to go with boy undies. She has ones like the picture below. Did you get boy ones that looks like this? Or more traditional boy boxers?
