They can't play on their own

Presence is not the same as participation

The single most useful shift is realising a small child usually wants you NEAR, not necessarily wants you PLAYING. Those are different requests and they cost you very different amounts.

The AAP puts the emphasis on parents' and caregivers' presence and attention rather than on equipment — it is that presence which enriches children, not fancy electronic gadgets.

So sitting on the floor with your coffee while they build, occasionally noticing what they are doing, is not a lesser version of playing together. For building independence it is often the better version, because you are not the engine of the game.

Let them lead, and let it be dull first

The AAP's description of what matters is playful learning where children take the lead and follow their own curiosity, and for imaginative play specifically, allowing play to be unstructured.

That is harder than it sounds, because an adult joining in tends to organize. We suggest, we tidy the narrative, we ask questions. Every one of those hands the steering back to us and shortens how long the child sustains it alone.

The gap at the start is the part most parents rescue too early. The AAP notes that some boredom allows for creativity — the flat stretch where nothing is happening is where the child's own idea has to come from. Filling it with a suggestion is the most natural thing in the world and it reliably ends the run.

What actually builds it

Start from where they are. If they manage two minutes, two minutes is the unit — leave while they are still engaged rather than waiting for it to collapse, so the pattern they learn is that playing alone works.

Stay in sight at first and narrate your leaving rather than sneaking off. Disappearing teaches them to keep checking; going to the sink where they can see you does not.

Fewer things out at once. A room with everything available is harder to settle into than a corner with three things, and rotating what is out does more than owning more.

Favor toys that do less. Something that lights up and sings performs the play for the child; a box, blocks or figures require them to supply the idea, which is the muscle being built.

Protect unfilled time. The AAP names tightly structured schedules as part of why play has declined — a child who is moved between activities all day has had no practice at deciding what happens next.

What is normal

Expectations here are frequently far too high. Very young toddlers manage minutes, not half-hours, and it is uneven — a stretch that goes well one day and not at all the next is the normal shape of it.

It also goes backwards predictably: illness, tiredness, a new sibling, a house move or starting nursery all reduce it for a while. That is a child spending their reserves on the change, not a lost skill.

The AAP thinks play matters enough that it suggests pediatricians write a prescription for play at well-child visits through age two — which is a useful reminder that this is a developmental need being met, not an indulgence you are permitting.
