One of my children has ASD, attended a special school and had severe behavioural challenges. I worked throughout his childhood but only because I was lucky enough to have significant support not available to many families..
My DH worked from home with a flexible, self employed job, so could be at home before and after school, and then was at home as the main carer during several periods where our SN child was out of school placement.
My mum also lives locally and was pretty much a third parent. And she was young enough when he was a child and at his most challenging ti cope with the energy levels he required. In her 79s now (DS is an adult) and she wouldn’t cope with it now.
There was no childcare available otherwise. No after school clubs or hobby clubs could meet his needs. No holiday clubs. He even lost local authority transport to and from school eventually because he was ‘too challenging’ for the staff to cope with.
I was part of a SEND parent support group when he was young, and the vast majority of mothers didn’t work. It was just too hard.
Work saved ny mental health, to be honest. It was a mental break from the relentlessness of parenting a child with significant needs and I kept an identity separate from being a ‘SEND Mum’.
