Not yet: show it once, then let them explore
Watch for the first sign: watches the water overflow from the little cup.
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 only the big cup and say 'full' and 'empty' as your child fills it and tips it out.
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: pours from one cup into the other using two hands.
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: hold both cups still, ask 'Which one is little?' and wait for a reach or a point.
Change only that one thing and keep everything else the same.
Ready for one step up
Hold both cups still, ask 'Which one is little?' and wait for a reach or a point. Or carry it somewhere new: point out big and little bowls while you unpack the dishes together.
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 only the big cup and say 'full' and 'empty' as your child fills it and tips it out.
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.
