i have nothing to suggest other than if she's wearing a skirt, see if she will wear shorts underneath instead of pants they feel different and she may wear them...gl xx
My DD always wore bike shorts under her skirts when she was young. The only ones my DD would wear as she was growing up were these: http://www.shopjustice.com/girls-clothing/boyshorts/panda-with-words-boyshort-undie/2791124
It's not just because they're boyshorts, but also those bands around the legs, kept her from getting wedgies.
Here to talk about mothering and more since I'm no longer TTC. I love to give support and advice!
