Daughter keeps getting bit at daycare. How much should I tolerate?

In the last month, my two year old daughter has been bit about 5 times and counting. It's from the same kid, we're pretty sure, but of course the daycare won't identify the biter. The daycare keeps saying "we'll talk to the child's parents", but it keeps happening.I know biting isn't uncommon, but this seems so systematic and my daughter hates going anymore. I know biting can happen anywhere, but how much is too much? via /r/Parenting https://ift.tt/2Ibz77V
