Piece by piece, he begins to recognize the picture that the puzzle represents. By inserting pieces into puzzles, he will develop the muscle group for writing, or the "pincer" grasp. As he grows and learns to rotate pieces to match holes and find pieces that fit, you can invest in more complex puzzles. What you can do To start with, you can find a puzzle with a picture that has a particular interest for your child. Help him recognize colours and letters and show him how sum of parts becomes whole.
