I bought this on a whim because I was looking for another toy by Learning Resources, which I think they must have discontinued. My baby was 6 months at the time and she loved it immediately...now almost a year and it's still a favorite. I don't know what makes it so attractive but any baby who comes over wants to play with it and becomes obsessed with the pegs/quills?, carrying them around. I like that they fit it for neat storage/easy travel and the pegs are numbered so babies can learn numbers as well as colors and work on their fine motor skills putting the pegs in the holes. Highly recommend!! And if they ever bring back that Learning Resources heart box of chocolates that puzzle piece together, buy it!
