Congrats!!!!! I got one and I thought it wasn't going to come until Dec. (per the rules), however I got it a while back, just 2 months after I won it. It's very cute!!! It's just perfect for my 18 month old. The 3 year old might like it for a short time but might grow out if it too quickly. The younger one can play on it, and will enjoy it for a long time. It is about 1-36 months ages. So, I would say give it to the younger one, big sister can play with it a little too!!
