@Corduroy: I recommend the Learning Journey puzzles. I have this one and my son loves putting them together.

My LO (23 months) is really into puzzles too. We just got a couple of these type puzzles when he got tired of the ones you have and he seems to like them. Definitely more challenging than the peg puzzles, but it still has the picture underneath for him to match.

@Myicitygirl: That's a great recommendation! I just ordered one for LO.
