DS wasn't diagnosed as autistic until 9. With hindsight between speech delays, multiple food allergies and sensory issues, our "late" toilet training at 3 actually wasn't bad going. We had a couple of normal range incidents in yR, but with dyspraxia, his dexterity at independence skills wasn't the best.
By the juniors years and now in secondary he tries his best to avoid school toilets. Fortunately this doesn't have continence consequences.
My concern is that there will be children at that age with undiagnosed, relevant SENs/ health needs involved that are discriminated against.
I couldn't have just walked out of work. Logistically between communications and cover, I was an hour away. Often there was no other contact avaliable. That's a long time to leave a child in that condition.
As it happens, DS's yR was the final year that I managed a work life balance without severely compromising his needs/ wellbeing. It's already tough working when you have a child with (undiagnosed) additional needs.
The real issue is a catalogue of problems of the provision of support (including diagnosis) to families and schools. There's a major lack of SEN provision; it's full of the most severe needs, so so many SEN children are sent to fail in under-resourced mainstream schools, and going longer and longer without diagnosis and appropriate support.
Where families have a lack skills, the loss of Sure Start and reduction of access to services like health visitors has made it harder to access quality support. Where families don't want to engage at all, it's difficult to get productive outcomes, but that's often not the issue.
