I love chunky puzzles they are fun and bright and make for great educational toys. They help with motor skills and if you describe all the pictures language skills. It hard to find puzzles that a suitable for little ones that still put everything in their mouth (you need to make sure they have no small pieces). Melissa and Doug has this great series of chunky touch and feel puzzles; each puzzle piece has a textured surface and is quite large enough for little hands.
Thank you memere and pepere for the great puzzle.
