This has probably been covered but most of the threads I have found have been related to children biting other children at playgroup etc. DD was 3 in June and has taken to biting her brother (5) and only him. No problems with other children at playgroup, in fact she is an angel but at home she is biting on average twice a week. Today she bit him so hard through his jumper it drew blood.
I'm at a bit of a loss as to how to deal with it, I've tried naughty step, putting her in her bedroom, speaking calmly to her, rewarding good behaviour but it just keeps happening. DS is no angel but he is never aggressive, her reason today was that he "pulled a grumpy face at her"
Most of the time they play well together, I think she's jealous of any attention I give him, he came home from school and I sat with him whilst he ate his snack not giving her undivided attention as before.
DH is of the opinion she needs a smack but I don't want to go down that route.
I know she'll grow out of it but it's not fair for DS to have chunks taken out of him while she's growing up....
I guess I'm looking for anyone who has had a similar situation and / or some advice on how to deal with it over the short / long term.
