Christmas 2012, I purchased a previous version of this ball (same features, but a with a yellow background) for one of my grandsons who was only 3 months at the time. At that young age he was an observer as he watched us roll the ball back & forth. However as the months went by, he gradually became a participant as he enjoyed the music & sounds when he interacted with it. He is now 14 months & I have watched his skills with this ball develop beautifully! He & his big brother, who is 4 years old, will sit & toss it back & forth (he's found it fun to throw things!). He sometimes sits with the ball between his legs, throws himself forward onto the ball & when sounds are forthcoming, laughs out loud! His brother & I play modified indoor soccer with it too. I love that they can't get hurt from this ball since it is so soft & it's also so easy for small hands to grasp. Thank you Fisher-Price! Your products have been delighting my children & now my grands for almost 50 years! In fact, my other grands are enjoying playing with my stash of 45-year-old "little people" that I keep at home for when they visit!
