Cardboard Tube Drop
A tube taped to the wall and a basket of things to drop through it.
One box, one slot, and a toddler who will not stop posting.
Cut a slot in a cardboard box and give them things to post through it. Endlessly repeatable and needs nothing you do not already own.
Posting is one of the earliest examples of a child holding a goal in mind and working towards it. Lining an object up with a slot requires wrist rotation and depth judgement, both of which are hard work at this age.
Every item must be larger than the childs mouth. No coins, no small lids. Keep the scissors well away once you have cut the slot.
Everything already lives in the box. Put the lid on.
A tube taped to the wall and a basket of things to drop through it.
A cupboard of containers and lids that do not match. Sort it out.
Reach in, feel one object, and describe it without naming it.
A tray of rice, some cups, and twenty minutes of total absorption.
A bowl of warm soapy water buys you a genuinely peaceful half hour.
A big box, some tape, and no instructions whatsoever.
