Out of what seems like nowhere, LO has started biting at daycare. One child on Friday and two today. Her teachers have been very kind and calm talking to me about how this can happen at this age and that she is not biting maliciously but curiously. I know that when the biting occurs (if it happens at home) I need to be firm and clear about how we don't bite but I'm at a loss to what else I can be doing to help. Does anyone have any experience? I feel so helpless.
