It's regular arguing over toys/time with me which escalates to shouting, DS(2 1/2) will then shove DD(7), occasionally with it escalating to a hit and kick if we've not interjected quick enough. Alternatively, DD will have a massive strop, try and snatch things whilst shoving DS, shouting and throw something in (in another direction) in anger, whilst stomping off.
Me and DH never physically fight and don't have screaming matches. Anything DS has seen would have been from DD who is sometimes like it with us when tired, or his daycare. We doubt it's the latter as DS has now started to mimick DD's throwing and stomping off.
We're trying to combat it with books for DS and explaining hitting, kicking and shoving hurts. With DD we explain what is and isn't OK when dealing with emotions.
The arguing and fighting this Christmas has driven me up the wall and I just wonder if we're really failing here or I'm being too hard on myself as a parent. DH says he and his siblings throttled each other regularly and it's normal, I can think of one or two instances with my brother but I don't want either to grow up thinking we didn't do more, when we should have.
