DD is 21 months, ds is 4.5 and loves winding her up. But that is no excuse, dd has bitten him 3 times in the last week. This is to me completelt unacceptable, but I don't really know the best way to stop her. The first time she did it I bit her(quite gently) back and used time out. The 2nd time I slapped her hand and used time out, the 3rd time I used time out and shouted loudly. All these times I have given Ds lots of attention in front of dd, so she knows she is not the one to be getting it. None of these have worked.
Very proud of Ds though, as he doesn't retaliate, and she has really bruised him.
Worried she will start doing this to other kids at nursery etc, just because she is not getting her own way
What else can I try?
(Hate smacking by the way, but I thought it was justified in the circumstances, I do not make a habit of it I can asure you).
