This is my son's second set of blocks. First he got up at 12-18 months, sat down, built towers, used them for target shooting, and they resisted all the bullying. However, since it's cardboard, they didn't get past its bite stage. It took 6 months but he managed to eat all 10 boxes. But they are useful when stacked both on top of and inside each other. The alphabet on the outside featuring Disney characters helped my son recognize both letters and symbols. He folded them up and down multiple times in less than 10 seconds. He loves building them and shooting them down.
