I had 5 - 7 yos and at first I thought piece of cake, no diapers, no naps, no strollers, school on most days and more flexibility to do special things over the summer.
But, attitude, and the "we dont do that at home" and "you arent my teacher", disrespect for me, my house and disregard for my rules that are more strict than they are used too.... I'm tired just thinking about it! LOL!
