Anyone else's 18 month old biting? Mine is apparently a little terror at daycare, but since she doesn't bite at home, I'm at a loss of what to do. I was hoping she would grow out of it, but it has been a few months now and her daycare provider seems to be running out of patience. I try to reinforce and practice sharing (she usually bites over toys) and bought a bunch of "no biting" books, but am out of ideas since I don't see it happen. Any advice would be appreciated!
