6-10 does seem like a fair time for a disco to me. I bet shes so excited. My eldest dd just turned 13 and she had a group of girlfriends over for the night and they all went shopping, to the movies and out for dinner..ended up being a great night. When we have had party parties at home, with a larger group of 20 its worked really well having other help, like granma or something, at least with the cooking and help with supervising. With that many children, there are always a few you dont know wanting to push the boundaries a bit..especially at 13. Have fun!!!!!!!!
