- Respond to whatever happens: "On! Tall tower!" or "Crash! Again?"

No level picked yet. The 0–4 scale is a learning log, not a test.
Not yet: show it once, then let them explore
Watch for the first sign: lets go of the block on top of the tower instead of dropping it beside it.
Not yet is information, not a verdict. Do it once yourself while they watch, pause, and offer it again in a few days.
Simplify one step
Next time: hold the bottom block steady with your hand while your child places the top one.
Give the least help that works: wait first, then point or show, and guide hands only briefly.
Repeat the same version and fade your help
As you step back, watch for: uses the second hand to steady the tower or the block.
Pause a few seconds longer before you model, and swap showing it for a point or a gesture.
Offer it once more, then add one change
When it is easy again: keep trading turns until the tower is three blocks tall.
Change only that one thing and keep everything else the same.
Ready for one step up
Keep trading turns until the tower is three blocks tall. Or carry it somewhere new: stack plastic food containers or boxed foods on the kitchen floor.
Starting it on their own or using it in a new place is the strongest sign. Still change one thing at a time.
Stop and rest this one
In 2-3 days, come back with the simpler version: hold the bottom block steady with your hand while your child places the top one.
End with something calming together. One hard moment never means a delay.
Stop on a good note
Keep this version and keep it short next time: 3 minutes is plenty.
They can do it, but it was not fun today. Add difficulty only once it feels easy and enjoyable again.

Why it works
Stacking two objects appears on CDC's 15-month checklist. AAP's toy report counts blocks among the traditional toys that support motor and spatial learning, most of all when an adult plays along.
Evidence rating: Good: published guidance supports the approach. Cited: CDC milestones by 15 months and AAP clinical report: Selecting Appropriate Toys for Young Children in the Digital Era (Pediatrics, 2019).
