Oh geez.....let's see.....9 is fourth grade......3 kids 6 and under.....no, that's not right. In fact, SHE can barely handle them, right?
That's a really good point, wdid! If she can't handle the stress of taking care of them, how can she expect a 9 year old do that?
I've read in articles/books that usually about 12 is the age that children are mature enough to take care of themselves, but even if your oldest was 12, which she isn't, I think that it would prob. take someone older than 12 to watch all the children as well.
