The Vtech rolling ball is a cute and entertaining toy for younger babies. It is great for babies who can crawl because they can push it and crawl after it so it encourages them to be active. It has different buttons that tell you shapes, numbers, and names of animals. I also love that it shuts itself off when your baby gets bored and stops playing with it for a while. It preserves the batteries. I have only had to replace the batteries once since I have had it and my daughter plays with it every day. It has many, many songs it plays and it plays a song to remind your baby to play with the ball...
