Since my little one is a premature baby, he needs a little help with the motor. The reviews of Oball were good, so I bought it with small concerns. The concerns were in vain. The Oball is an integral part of his game ritual. At first the ball was observed with his hands, then with fingers and mouth, eventually kammen off the feet. The Oball is now in the bassinet or on the floor always with. While he plays with something else, the feet with the Oball on juggling, back and forth are pushing, between the legs, etc. The leg muscles and movements have greatly improved! Always my pleasure. However, one can not choose the colors :) How did a Pink-Purple ball get ....
