This eco-friendly colorful car puzzle has big, chunky pieces which are easy for toddlers to grasp. Also, introducing puzzles with only few pieces gives a child confidence. I first introduced it to Adrian when he was a year-and-a-half. At almost three years, he still enjoys it. I like a toy that "grow" with your child: even a one year old can enjoy holding these chunky pieces of solid wood painted with bright, non-toxic paints.
Eventually, a child will be able to assemble the car free-standing.
