dd2 has recently bitten dd4 - once quite badly!
I'm not sure how to handle this - I have twice put her up in her cot for 5 mins until she agrees to come down and say sorry. Is this the right tactic - I think she still enjoys the attention from being put upstairs, so I wondered if an ignoring or paying more attention to the victim would work better? I obviously want her to learn that she does not bite anyone.
