well, the other thing i wanted to mention is, with SA, you have to lay down the law right from the start with them, or they will walk all over you. don't let them get away with anything!
find out what the girls are really into, and maybe even ask them for some ideas. when you involve them more in the decision making, they are usually more willing to comply.
My SA love crafts, art stuff, legos, polly pockets, the marble run, cooking, science experiments, and helping me with the little kids. the boys like computer games, of course, but they have to earn those priveledges here.
