How do i go about stopping this behaviour?
My DD has hit the i won't say terrible two's as generally she is pretty good and most her tantrums were she would scream for a bit throw herself down and after a talk from either myself or DP she was fine. Now it seems she is lashing out physically at myself or DS.
Just a moment ago DS was in his rocker happily sucking on his dummy, DD who isnt allowed to have a dummy during the day unless its nap time walked over and wanted his. I said no, she kept trying to take it and i said "if you take it out of his mouth you will be in big trouble" which seemed to just provoke her and make it into a game. When i wasn't looking she took it and put it in her mouth, because she has the chicken pox he now can't use that one until i sterilise it. I took it out of her mouth, told her she was in big trouble and i would now turn cartoons off. Quick as a flash she let out her usual squeal when shes chucking a tantrum, came over to me smacked my arm, smacked the couch then walked over to DS smacked him then pulled at his clothes quite roughly (he was oblivious to the whole thing, still sound asleep) but it was quite alarming that she was that mean to him.
We use time out and smacking for discipline but both of these don't seem to be working. I have tried telling her that she has to be careful with DS as he is only little and she will hurt him but being 2 she doesn't quite understand.
So just after some advice on how to go about it as i would love to get on top of it before it escalates and i have a serious issue on my hands.

Distraction and interception are the best way to handle these types of situations. If you can see the signs that something is going to work into a problem don't wait to react. As soon as I saw her near the baby I would have been interfering simply because she is so young and unpredictable. I would have gone over and 'talked to her' about bubs, about her being a big sister, about how to touch 'gentle' (or even 'no' touching)' and I physically would have intercepted every time she reached for the dummy, said no firmly but quietly and tried distraction again. If she persisted I would have again said 'no' firmly and then physically moved her (without anger) to a different part of the room or house and distracted her with something else.
It is natural reaction for toddlers to lash out physically, as a parent our job it to try and guide their behaviors so that this doesn't happen, if it does (and it will at some point) you let them know what they have done is wrong and again remove them from the situation. It isn't enough to say no, to punish, you have to remove them from the situation and get them focused on something else.
I am by no means anti smacking (all my kids have been smacked occaisionally) but I don't think that this situation is one where it would be useful at all. She is simply too young to understand that her actions impact someone else and that she can 'hurt' others. She is just trying to get a reaction and attention. If you can give it to her 'before' she gets aggressive you have already won the battle and she has had her needs met. ;)
