This horse was my wife recommended in a baby course from another mother. The principle is simple, you shake this horse and there is 1 of 3 sounds. I was really skeptical because I think it looks very strange. But my daughter loves this horse really. She has also worked with your 6 months to shake any difficulties this horse. If one takes with this horse in the car, you should just look how it puts in his pocket, otherwise you hear while driving always a whinny or the gallop of a horse. this can also be very funny.
