The sit-and-stack stage.

Illustration of Lukas sitting on a tan quilted mat in a cream romper, holding a red ring over a ring-stacking tower, a soft block beside him
Lukas, sitting up and stacking, very pleased with himself. He's imagined, not a photograph — but the pride of a first wobbly tower is something every parent recognizes.

Sitting up frees both hands. Things get passed hand to hand, banged together, dropped on purpose, and fetched back — cause and effect, rehearsed at full volume.

Stacking, nesting, and rolling fit the stage: toys that pile up, topple over, and come back for another round.

Two voices, attached to the picks themselves: a speech bubble from Chris is a note from our home, in his words; a bubble from Hiro (the lamp) calls out a standout — paperwork, developmental focus, or safety record. No bubble means no note for that pick.
