While we were out of town, we visited The Land of Nod. (if you've never been to the store or website, you should...they have the best stuff!) I got this color sorting puzzle for A. I really wanted to buy this one but it was twice as much and I thought it might be too hard for her. Well, I introduced the puzzle to her on our car trip, and she got it almost instantly! It's a fun, simple activity and I was really impressed with the quality of this product. Even though she's mastered this puzzle, I think she'll find it fun to play with still for a little while.
