Melissa & Doug Chunky Puzzles (4-pack)

The chunky M&D puzzles are the standard against which all toddler puzzles get measured. Each piece has a fat plastic-free wooden knob, the puzzle pieces themselves stand up (so they double as figurines), and the four-pack covers vehicles, animals, dinosaurs, and pets. A 2-year-old will start with a few pieces and be doing the full set unaided by their third birthday.
