I try to avoid telling a 3 year old what they are incapable of doing.

The 3 year old will tell you what they want to do.

At 3, my little guy's favorite toy was rated for 8+ years old, and his favorite game was chess.

He never cared if he won or lost at chess, his primary purpose was to push his pawns, castle, and then get in at least one en passant.
