We got Mr W those wooden puzzles with the knobs on them a few months ago.
He was fighting me to get the puzzle out of the plastic wrapper.
When I put the puzzle on the floor, he took all the pieces out, put them back as designed, then took each piece and systematically tested it in the other holes.
He then took the round piece, put the knob in his mouth, the piece covering his whole face, and crawled to his next toy, then tried to use that piece in its slots.
Nowadays, sometimes, I will take a piece and put the knob in my mouth, and he will laugh, put one in his mouth, and we will wait for DW to come into the room.
I'm sure he will fail his evals when he is 5 due to Dad encouraging his weirdness!!
