S.T.
We got one for my daughter for Xmas (she was 18 mo). She is 22 months now, and loves playing with it still. When we have play dates, the boys can't wait to play in the kitchen. They enjoy it just as much as the girls in the group.
We bought a Step 2 kitchen from the company's website. They are a little more expensive at the start, but they come with the dishes and the food. They have wonderful noises they make and I don't regret buying the one we got one bit!
Your daughter will also enjoy it when she gets older as well.
