Absolutely agree.
I have twins. DS has clear learning difficulties and diagnosed as autistic aged 3, other diagnoses followed. Now 15 yrs old and still in nappies/pull-ups. Everyone would have known his SEN meant toilet-training was challenging.
His twin sister had difficulties, and was still wetting at night/having day accidents when she was 5. Finally got there but dear god it was a slog. At that age she was believed to be neurotypical.
And then…
At 10 years old she was diagnosed as autistic, and with additional language difficulties that put her below a 6 yr old for comprehension. Very significant SEN. Despite the school supposedly being outstanding for SEN, teachers failed to notice her difficulties for years because she was “quiet”.
If anyone had seen her between the ages of 4-10, you’d never have known she had SEN because she flew under the radar. You’d just have thought I was a crappy parent, despite being seen by the continence service and doing everything I could, to no avail.
This is why judgement matters. For everyone saying “oh, I only mean children with no SEN!” - the point is those children/parents you’re judging for “not trying”? There may be undiagnosed SEN which may not be picked up for YEARS. Especially in girls.
