Also, I'd like to second the previous poster who said that if she's smart enough to throw tantrums this young, she's smart enough to move on to something else as soon as she's capable. This was my experience as well - despite all those dire predictions about the 'terrible' twos, my son has been increasingly pleasant, reasonable and generally easier in direct correlation to his increasing communication skills. He's 2.75 now and I've found the "twos" to be an absolute delight... I tend to tell people he had the "terrible zeroes" instead.
