but an hour or two of therapy a week is useless without continued support from home and from other caregivers such as schools or nurseries.

For sure. And I don't think most parents, however they might "know" about it, are actually equipped to provide the support necessary. And schools, well, they struggle to support kids without learning difficulties - so their chances of positive effect are slim.

All too many parents see something 'not quite right' in their toddlers but then put off asking for help, hoping they'll 'grow out of it'.

I think it goes the other way a bit here - parents see everything wrong, and want early medical intervention, through medication.

This can be especially noticeable in reading and writing. Kids who drop behind can become self-conscious leading to behaviour issues, self-esteem problems etc etc. It can rapidly become a downward spiral.

And, this is another problem for the other children in the classes too. They put everyone together, even though needs are very different, so everyone suffers.

Even if a child is only watching and playing educational videos and games, it is one-way learning and there are no communication or social skills being developed which in early years is of utmost importance.

They feed into the dopamine cycle. They aren't necessarily learning through those games, they are just getting that tiny hit of dopamine that keeps them coming back. That is unsustainable long term for learning.

Thanks for adding your thoughts on this here!
Hope you have a great weekend too.
