My DD has some strange behaviour that I REALLY hope you can all help me with. Whenever she sits in her highchair or car seat she kind of kicks her legs and its almost like she's rubbing herself against the belt or that big safety thing between her legs-sorry cannot remember what it is called! Its causing deep red marks where her nappy digs into her legs, but I also don't know if it is something more-like she emjoys it. I'm sure it can't be that but I don't know how to stop it. Please halp
