Perhaps a little sister or brother? No I wouldn't wish that on you, unless you want to giver her one of course. Children that age are fairly easy, Surely clothes are always a hit, and at that age always needed. They grow so fast. Dolls are great, and the standard domestic fair, like toy stoves and grocery caskets with plastic veggies. Some might think me sexist for suggesting them but my daughter played with hers for hours, with my son so they both learned a lot.
Kids that age are easily entertained though so don't feel like you need to get too fancy. A card board box is a wonderful toy. I've never seen a child that didn't enjoy playing in one. Not sure I'd give it as a present exactly but it shows that it takes a lot less than some parents think to please a small child. Then again it might explain why my kids always gaze at me with that "What was he thinking?" look even today.
