i'm definately going thru this too.

ds doesn't throw food on the floor any more though and I found the best way to deal with that was to ignore it. I know its hard to ignore bad behaviour but I found that he did it more when we told him not too. So once we started ignoring the behaviour, he stopped doing it.

There isn't much you can do about tantrums, I find to help ds through it and explain why he can't do "whatever he is not allowed to do" helps him and his tantrums only last about 30 seconds tops.

Could you perhaps move the glass coffee table where she can't access it? Our ds is constantly standing on the couch, which is not allowed because he is sooo clumsy and he falls off onto his head. The way we deal with this is to send him to timeout for 5 minutes to give him time to calm down. It usually takes 2 goes at time out before he stops standing on the couch. Perhaps try timeout with your dd.

Timeout can be anything from sitting in the highchair, or going to his room to play or watching a dvd, just something to get him to calm down and forget about standing on the couch.

Headbutting is a big thing here too as is pinching, I haven't yet come up with a solution to that one so hopefully someone else can suggest something.

Good luck and remember it doesn't last forever (thats what I tell myself every day lol)
