DD is going to be 3 in 2 weeks, and shes just started biting! we tell her no, we dont do that and that hurts etc, but is there something else I should be doing? tips?
At 3 mine would get a time out as well.
I'd try to figure out WHY she is biting. She's probably doing it because she's frustrated and can't articulate why. In the end, it's a phase and she'll stop once she can talk better. Until then keep detering her, help her find ways to express her feelings when she's frustrated, and figure out what triggers her most that way you can be proactive rather than reactive.
