I do agree that time outs do not work for every child... for example, my 6 yo ds. He has special needs and his temper can be an issue. What works for him is losing toys or games. Just recently he let his anger get the better of him, and decided to throw his nintendo ds, cracking the screen. He lost electronics as a result. Now he needs to work to earn that privilege back.

I understand that may not work for your daughter either, especially as she is so young... but as it's been stated there has to be some kind of consequence.

As for the other kids respecting her space, as the other ladies said, this is also a must. Some people just need more space than others and there is nothing wrong with that.
