Query: Wonderful and helpful

I bought this barbie for my 4 year old daughter. I am pregnant and due in a couple months. I found it very helpful not only to show her where babies come from, but also having the whole setting of the mother, father and brother and even the nurse. She loved it. It has made her more excited and more in tune to what is coming. It's wonderful!
