DD2 now strong enough to fight, help please?

[JackBauerisreadyforDay8]

I have 2 DD's. 3.11 and 2.3.
DD1 is very vocal and also quite selfish/stroppy/drama queenish with what she perceives as 'her' toys.
DD2 is just physical, her talking isn't great and she is mostly very laid back but when they deicide to fight they will fight DD2 bites, punches and kicks, DD1 doesn't fight back unless severley provoked (she will push Dd2 away if she is bitten, fair enough)

DD2 is also starting to run around and just shove DD1 over for hahas. She is very clever and knows when she is wrong, so she will apologise and come for cuddles or be all cute to get herself out of trouble

We spend the time at home downstairs in the front room, as that is where the toys are, upstairs is not an option for DD2 but soemtimes DD1 will go on her own but she likes to be downstairs playing.

What do I do when DD2 bites/hits and then laughs? We have resorted to time out in the hallway as DH tried it once when I wasn't in and it worked, but that just involves yelling at her to stop what she is doing and sitting her down. She stays and then comes out a fwe minutes later wreathed in smiles and apologies and then carries on with whatever got her in trouble in the first place!

Any advice/sympathy/experience very welcome!

Anyone? Sorry it's a bit epic!

Bumping as DD2 has just bitten DD1 on the tomach so hard she has broken the skin through 2 layers of clothes

i think its a matter of discipline.

if you are going to send her to the corner, don't smile at her when she comes back. show and tell her in a firm voice that you were very upset with what she has done...and explain the consequence of this action, Follow through with the punishment ALL THE TIME...

She needs to know that you do not take kindly to her misbehaviour

Otherwise you will have a bully on your hands when she goes to school full time

I do all that, she gets sent to the back hallway, no eye contact, no talking, then after a few minutes for us all to calm down I bring her back in and say 'No biting, we do NOT bite' and she repeats no biting, sorry mummy'
Then a few days later she does it again.

Is it something toddlers normally grow out of? She isn't in school at all atm, she is only 2.2 so am hoping it's a phase DD1 missed out on.

I think I read somewhere that toddlers often know something is wrong but can't over-ride the compulsion to do it. I guess the only thing you can do is to continue with the discipline. My DD is 2.4 and I am already at the stage where I take things away if she is repeatedly naughty ie whatever she's playing with most at the time. This does work although she makes her displeasure well known.

That makes sense. It is only her sister she bite now, and normally over a shared toy that neither wants to share.
