Parents Burning feeling/hands on bars even with grips?

[Kcanflip]

Anyone have any suggestions to relieve the burning hands feeling caused by extended time on bars? my DD does wear grips. She is also older and taller... 5'3 at 13 so heavier than the average little gymmies. It sounds friction related. No rips... Just intense burning feeling. Can she use something on her hands under her grips to help with this? Or is it just the way bars is?

Probably should have just added this question to the other thread about blisters... Oops. Sorry about that.
