Hi Girls (and guys)
I have a 2 yr old DD and a 8mth old DS, lately DD has been hurting DS, such as biting his head and hands, scratching his face and head pinching him etc. He looks like he has been in a fight with our cat, people say "Oh somebody looks like he has been tormenting the cat" but seriously its DD that has done it to him and I cant remember the last time I saw his face/head clear.
They are not random attacks she is doing it when he goes to touch her toys, he is just exploring but she doesnt know this, I have explained it to her, she is a pretty switched on little girl but is very protective of her stuff.
I feel like I have tired everything:

Taking the toy and putting it away for a long period (some days there has been more toys in my walk in robe than in their toy room)
Time out
Going to room
Sitting down and explaining it to her how its not nice etc
Smacking her
doing it back to her
The latest thing I tried was just ignoring it picking DS up and walking away with him but sometimes its hard to not react when she is so rough.

I am just wondering if there is something else I can try or do I keep peristing with these things and eventually she will get it - is there something I am missing.

Hope someone has some strategies for me.
