A super invention! ... The ball I had seen in the course at a Mama Pekip and my little one took him then just great ... My daughter is jetz 3.5 months and will also be much intressanter hochzustützen when the ball before her lies. The little ducklings swims always on top by the weight and the colored beads are also an eye-catcher. Later she crawls then determined as the Great already behind the ball ... The ball has been constant companion at that time. =)
