My Boy can finish 16 pieces puzzle

In previous post, I mentioned about my boy likes to play puzzle and manage to complete 16 pieces puzzle after we taught him for a few times. After that, I started to bring out those puzzles I bought before for him to play.

No matter how active this little cheeky is, when the time playing with puzzle, he will sit quietly, focusing on those puzzles and put in all the pieces together.

Herewith one of the puzzle my sister bought for my boy. After we played together with him for a few times, he managed to complete the whole puzzle all by himself.


After 16 pieces puzzles, what is next? 24 pieces? But I can't find any 24 pieces puzzles in the market now? Where to buy?
