Yes, I did it ( 2 years 3 mos)

Mommy found it amazing, cos today mommy gives him his old 4pcs, 5pcs, and 6pcs puzzle and he did it all by himself, little help from mommy.
His brain is somehow ready for doing problem solving, mommy's so happy when he did it and he has very much interest in puzzle these few days.
Perhaps he also saw mommy solving 100pcs and 300pcs jigsaw puzzle therefore he has interest in it.

Anyway, Well done boy ! mommy is so proud of you
