((((((((((((((((((Mel and daughter)))))))))))))))
When I was in 6th grade I started my period and my mother sent me to school with one of those paper bags that you put your lunch in. She filled it full of maxi-pads and off I went to school. While on the bus ride everyone kept asking me what was in the bag and I refused to answer and the boy sitting behind me snatched it out of my lap and starting laughing and then ofcourse, the whole bus knew. I was so embarressed and just wanted to curl in a hole. I told my mother but that fell on deaf ears.
My advice is to call the school and speak with the school councellor, principal and your childs teacher. I would explain the incident and tell them that it is unacceptable what happened and that you demand that the persons involved be delt with.
I understand how your daughter feels and I am sorry she is going through that
