I think this is a big contributor. All people have sensory needs and limits (both ways, lots and none), not just those on the SEN spectrum. A lot of children are having high levels of visual and auditory stimulus with little input from parents. Babies and toddlers are routinely given screens in buggies and on journeys, rather than taking any of their surroundings in. Even in nappy change, they’re distracted by a screen rather than feeling the sensation of the change and interacting with a parent.
There are lots of other contributors too. Families are often stretched to the limit, there are high levels of poverty, parents and children are struggling to access health care, early intervention services are gone or overrun, both parents are often in full time work and trying to cover childcare and the cost of living is really high.
SEN provision is a nightmare with the process set up to be really complex. Agencies ignore that many of the parents are ND as well, so need clear pathways. There’s a struggle to get help for children who are non-verbal and have severe learning difficulties and physical disabilities, let alone children who are high functioning. As the parent, you can put in place everything and still feel blamed. We’ve been parenting with therapeutic parenting and PACE for years, our ds masks at school, the school believe us but there’s such a nightmare trying to portray this (common) situation via the process. In our situation no one even seemed to be able to clearly tell us next steps until the school got hold of the psychiatrist who will eventually assess - and we’re lucky as we have a supportive school. Parents have to go on a parenting course and a workshop for ADHD - which if done together are two full mornings a week. Obviously, you do them, even if you’re aware of what they’re teaching already, but the reality is it’s hugely stressful to balance that, full time work and parenting an ND child plus all the paperwork you need to write. The forms are crap (fit early development into a 5cmX8cm box for ASD), so you end up writing a huge document to attach. IDPs are like gold dust and there are strict remits that don’t suit children that appear to function but are highly affected at home.
Equally, the ADHD workshops are too light on the risks of screen time (lots of correlation between addiction risks with screens and ADHD) and huge numbers of children are isolated with their screens without the support they need to educate them or help them manage their symptoms. There’s a huge focusing on adjusting parenting techniques, but no advice when you’ve done that prior to all of this and that’s why you sought support and diagnosis in the first place. I appreciate course leaders say parents in that position are in a minority, but there must be plenty of others who have done this and, for them and for us, there’s just a very punishing process in which the child’s voice is often lost and the parents are blamed for trying to advocate for a child that needs support.
