I don't know, it should be an interesting battle at our house! I have to constantly talk to DS8 about calling DD5 "stupid". She can read now, although she still guesses on unfamiliar words, but he thinks she should have known 3 years ago like he did at her age. It's hard for him, because practically everybody is "stupid" compared to him, so he can't see that she is really a pretty smart girl. She just isn't on his level, but he doesn't know anybody who is. I'm hoping that at least this will translate into her trying to show how smart she is, rather than hiding it, but that could lead to a whole different can of worms if she's always trying to catch up to brother who is not only on a different level but also 4 years older. She seems pretty oblivious to it all so far, which might be the best course.
