Just a little perspective, mine have never been in day care in their lives yet in the toddler years there was always a bruise, a black eye, a scratch, bump, or bite mark from siblings. Its hard to see your kids get hurt. When its on your watch your realize its inevitable. But on someone else watch, you always have to wonder if there was adequate supervision. But anytime kids are in groups, this stuff is bound to happen no matter how much supervision there is.
