Did has just told me that a friend of hers in her class (Reception) has been pulling down her knickers and rubbing her vulva. It has happened on more than one occasion in the toilets and whilst changing for P.E. She told me that she told the P.E teacher and they didn't do anything. I will be speaking to the class teacher on Monday. I know the mum, should I speak to her too or leave it to the school?
