Puzzled

what has our little guy been up to? He's been doing puzzles again and again and again. He loves his little set of 4 vehicle puzzles. I love to see how he learns and picks up the concepts. A few weeks ago the puzzles were a definite challenge. He would have edge pieces consistently turned upside down as he tried to work them in place. Now he's zipping along! I wonder where he gets his love for puzzles from?
