I feel your pain. I too, am counting down the days until my daughter goes to kindergarten, and I send her to preschool two days a week. My son who just turned two is also starting to become a problem, so between the two of them, I never have a good day! I am going to send him to preschool in October like I do his sister, so I can get a break during the week. Part of their problem is that they are more advanced (not to be biased, but they are) than the other children I have in care, so they get frustrated when the other kids can't/won't communicate with them and then act out. I do let them go off on their own, but then they start fighting with each other.
