My DS is 19 months old and attends daycare three days a week. He was bitten on the cheek yesterday, which makes it the fourth time he's been bitten at daycare in the last three months or so.
Three of the bites, including yesterday's, have been hard bites. They cause DS to cry, break the skin, leave a bruise, and scab over. Two have been on the cheek and one was on the back of the arm. The fourth was a gentle bite on his wrist and just left a red mark that went away the next day.
Of course, the DC can't tell us who did it. However, according to his teacher, all of the hard bites that break the skin have happened when he was minding his own business and, each time, DS tells us that the same child, "Tara," did it.
Obviously, we don't know if this is true, but he's almost always correct when he talks to us about other things that happen during his day. On other occasions, when we ask him about his friends at school, he tells us what those friends like to do and it often changes from week to week. Yet the only thing he ever says about Tara is, "Tara, bite," and he shakes his head.
Similarly, when he got the gentle bite on his wrist, DS told us the name of a different child, "Ross." In that case, the teacher told us that DS had taken another child's truck, so at least that bite was provoked.
Each time DS gets bitten, the DC writes up an accident report and tells us in person without telling us the name of the child who did it. They also talk to that child's parent. If what DS is telling us is true, it seems like Tara is developing a habit of biting DS without provocation. DS is a pretty amiable child and usually minds his own business. His personality is not at all aggressive.
Would you talk to the director (and what can they do?) or the teacher or would you just chalk it up to the age of the kids? I know this is a prime age for biting but he keeps getting bitten hard for no apparent reason and it's upsetting.
