I think three-year-old children still play mainly, and of course they can play more intellectual toys; Today's early education robots are also a good choice. Early childhood education, recommend a small martial arts robot. Exercise hands-on ability in play and learn to think in play. If children are interested in farewell, they can also attend training classes, but don't emphasize the results. After all, their intelligence is limited. I remember there was a newspaper about early childhood education, which was specially aimed at young children and proposed different hobbies according to different age groups.
