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: tries a lid on more than one container before it fits.
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: use one container and one lid, so your child only has to line it up and press it on.
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: turns a lid to line it up with the rim.
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: add a third container and lid.
Change only that one thing and keep everything else the same.
Ready for one step up
Add a third container and lid. Or carry it somewhere new: put lids back on pots and pans with you while you tidy the kitchen.
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: use one container and one lid, so your child only has to line it up and press it on.
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: 5 minutes is plenty.
They can do it, but it was not fun today. Add difficulty only once it feels easy and enjoyable again.
