Using these puzzles is easy. Just let your child pick up the puzzle pieces and try to fit them into the right spots. It's a great way to develop their hand - eye coordination and problem - solving skills. When your child is done playing, make sure to collect all the pieces to avoid losing them. To keep the puzzles in good condition, wipe them with a dry cloth regularly. Don't expose them to water or high humidity, as this could damage the wood. Also, keep them out of reach of younger children who might put the pieces in their mouths.
