Query: Three year old loves it!

My three year old loves this puzzle, and can do it by herself easily. My only complaint is that within a day of playing with it, a couple of the pieces warped. This is not the first Melissa & Doug puzzle I've bought recently that's done that. One piece is so warped it's hard to fit it with the other ones at all, but as it's the corner piece we just lay it there and are done with it. Still, M & D puzzles are great for little ones.
