Rubbing herself

Does anyone else have a 3 year old who “rubs themselves” against their car seat? Have you figured out a way to get them to stop? It’s almost non stop with my daughter from the time we get in the car, and it’s very uncomfortable for any and all to witness...

Update: she is humping the car seat buckle. It’s also not healthy to do it the amount she does. She could rub herself raw.

It is unacceptable to do it in public, normal or not. (I understand that this is normal behavior. We need to train her not to explore her body in public.) This is not my first child. We were able to teach our oldest not to do that in public. For some reason, it’s not connecting with her.
