Optional
- a soft toy to sit on top
How to play
Stack three cups or blocks while they watch.
Let them knock it down. Knocking down comes months before building and is not naughtiness.
Build it again, a little taller.
Around eighteen months, hand them a block and see whether they place it on top.
Count each one aloud as you stack — the counting sinks in long before they can say it.
What it helps with
Keep it safe
- Build low and away from hard edges.
- Blocks must be too big to swallow.
Make it different next time
- Nest the cups inside each other instead, which is much harder.
- Balance a soft toy on top for a bigger collapse.
Cleanup: Nest them and put them away together.
