Nolan loves to play with all his toys, but he loves his toys that are balls! I think it started with the Hasbro busy ball popper, and then he realized he could throw a ball for Wrigley and she would bring it back to him. So I found 200+ balls and put them in the pack n play and made a ball pit. At first he was very hesitant, but I kept putting him into the ball pit for a short period of time. And sure enough, now he absolutely adores his ball pit. His favorite thing is throwing the balls out of the pit onto the floor!
