Need advice. Normally placid 5 yr old started pushing, shoving and hitting sibling

[DiscoDizzy]

DD1 (5) is normally very placid if a bit selfish, goes through phases of sharing and not sharing etc. DD2 (3) has always been the spirited and temperamental one who more often than not will share and isn't so selfish. DD2 has always been the one to push and shove etc and has been reprimanded for it, its now calming down, however DD1 has now started with the pushing, shoving and hitting. She admits it when asked about it and its usually because DD2 won't listen to DD1 or won't hand something over (thats DD1's). I need a strategy to nip this in the bud NOW. Please help.

No advice really except try to deal with it calmly and perhaps feel a little bit proud that your dd is sticking up for herself. They will resolve it, has dd1 recently started school? When my dds fight I often try to ignore it and they stop as quickly as they started, if I get too involved it goes on for ages.

Thanks cherryred. I do think she has finally started to stick up for herself, she started school last september and loves it. Unless anyone comes on with any pearls of wisdom, i'll try to ignore it. I don't want her becoming a bully to her sister. Its been so unlike her.

I think it is a really confusing time when they start school, I've got that to look forward too, they probably want to play more grown up games and younger siblings get really irratating. I have no tolerance for violence but squables tend to just happen a lot.
