I made this game for A when she was 15 months old. I cut holes in the bottom of an egg carton, and stuck clothespins in each hole. A would carefully take each clothespin out of the hole and then try to put them back. She played with this toy a lot and if I bring it out, she'll still play with it. I remember her having a harder time putting the clothespins inside the holes than taking them out. Now she's a pro and can do both quite easily.
