This document discusses reasons why toddlers may bite and strategies for preventing and responding to biting. Common reasons toddlers bite include experimenting with their new teeth, seeking attention, or trying to communicate. Teething can also cause biting as toddlers try to soothe their gums. The document recommends separating biters from frequent targets, shadowing or isolating biters when possible, keeping biters occupied with toys or teethers, attending to bite victims first, and firmly telling biters that biting hurts when incidents occur.
