My son is about to turn 2 in two weeks (!!) and we are expecting a little sister at the end of May.

I was planning on getting a Manhattan Stella doll for him but would you get a girl doll, as the little sister? Or a boy doll to be like him? I mean, he doesn't really know the difference, and really it comes down to color, but still, what would you do?
