My son got this toy when he was about 8 months old. At this point, I had to play with him and help him push the balls down as he watched them go all the way to the bottom. He loved to watch the bottom to see which exit the ball would come out of. He seemed to lose interest in it for a couple of months, and I was a little disappointed. He is now 12 months old and has all of a sudden rediscovered this toy. He loves it!!! Plays with it all day long. Unfortunately, he now tries to put anything and everything down the ball chute along with the balls. I have found it to be very sturdy. My son weighs 27 pounds and has only managed to flip it one time. He pulls up on it all the time. I would definitely recommend this toy.
