There is a child in my wider family who has been diagnosed with autism and another who is currently being assessed.
I can see how hard life is for their mother. The older of the two children has no idea at all re safety and would run off all the time if they could. They go through phases of putting non-food items in their mouth. They have an obsession with a particular cartoon character and want to watch endless repeated one minute extracts from the relevant films/programmes. Not toilet trained. Wants to be spoon fed. They are non-verbal
The other has a significant speech delay and tantrums a lot.
My husband and I try to help. We have read stuff, listened to the children's mother and seen her in action. We know she loves the children and is doing her best. We understand how tired she must be.
We also know that there are times when she is not well, because her own health is suffered. Sometimes the children will spend quite a lot of the time strapped into buggies etc when out, because if it is just the mother and the two children, the older child will run off and try and jump into a pond or run into the road.
But we also think - as we'd think with NT children - that there are things we would do differently.
Quite apart from issues around neurodivergence, we have observed the shift towards a much more child-centred and protective form of parenting. We come more from an era where the focus is on enabling children to grow and develop through laying down secure boundaries and through instilling socialisation around say, learning to feed yourself and sitting round a table - not always 'waiting until they're ready.'. Having active play and limiting entertainment via screens.
We do our very best while visiting the children's mother to relate to the children at the point where they are now. But I've found that even, say, suggesting I take the younger child out of the buggy where they are staring at their mother's mobile phone - because I'd be able to supervise and keep them safe - will result in a snapped, 'They'll let you know when they're ready to come out.'
So all I'm saying is that sometimes it can be very hard to help, unless you are willing to be the equivalent of the nanny who is paid to do exactly as the parent instructs. (There is a part-time nanny.)
Sometimes because it is so hard and relatives can be made to feel that anything they do is the wrong thing, they just opt to step back. And then they are made to feel in the wrong as well.
