DS was referred at 2 year old by his allergy consultant of all people, because he just lined up all her equipment, would not make eye contact, didn't respond to his name and the very very limited number of words he had, and I mean limited, maybe 2 or 3, he just stopped using them.
He was diagnosed by 3 years old.
He didn't play with toys rather that he investigated how things worked by disassembling them or played with cause and effect by being destructive. It looked like typical naughty child behaviour but to him he was learning that if he does this, then something will happen and sometimes those things can be fixed and sometimes they can't. It was a hard adjustment accepting he needed things to throw and destroy and there would be a never ending cycle of picking toys up and putting them back together, but it was necessary for his development.
He went to nursery, they all observed his struggles. It really felt like we would have a permanently non-verbal child at that point. He would not engage with anything at all.
He didn't respond to pecs symbols and had no interest in low or high tech AAC.
He had 3 rounds with speech and language, who at the time did not understand or weren't trained to support gestalt language processors so would support in a very neurotypical oriented way.
My son would rewind videos or insist we watch the same programmes on repeat, and that's when I did my own research into gestalt language processing and how to support it, by his third bout of SALT they'd received statutory updated training on GLP so it finally felt like we were all singing from the same hymn sheet.
He was not toilet trained before starting school and I feel like I didn't get the right support from nursery to support an EHCP application, however when he started mainstream, although it was apparent they weren't the right setting they've been fantastic about supporting us to get an EHCP and specialist provision, as well as supportive therapies for various areas of development like maintaining attention and taking turns. Life skills that don't come as naturally to him as it has others.
He started talking within 6 months of starting mainstream, and he is still catching up with his language now at 6 but most of his needs he is able to communicate verbally even if we're not having conversations just yet. He understands everything that is being said to him and around him and he is always soaking things up and every week he comes up with something new. Like his first time asking a question for curiosities sake, or his first time calling me a funny name. All the firsts that most parents take for granted.
It has taken a lot of hard work and self research to get to this point because the public knowledge within the health service just hadn't caught up when we needed it.
He is 6 now and he is awaiting a named specialist provision on his EHCP, but he is so capable, but he is just so different too and easily misunderstood.
For example if you ask him if he wants something and he just walks off, it usually means yes I want that im going to sit down so you can bring it to me, but it's easy to see his walking away as disinterest unless you know what his non-verbal communication looks like specifically.
He still leads by the hand for things he wants when hes had a long day of interacting with the world.
Sometimes he will just say juice, or milk, and not "I want", and offering him choices is just too much and he will have a verbal shutdown and you won't get any interaction from him.
He's still not toilet trained fully, we've just about got weeing but he can't always tell us when he needs to go. We haven't got pooing down yet at all.
So yes, life is still difficult for us, but it's no where near the life I thought we'd be living.
He's made no academic progress at school but he's entirely capable he just isn't being given opportunities that meet his way of learning just yet, so we are hopeful that specialist can help us. He's resitting reception for a third year until specialist is named.
However he turns out, our life is richer for having him in it, even though it is incredibly hard work. He doesn't sleep, he elopes in some quite frightening situations, he still needs a pushchair for his safety, he can't tell me how his day has been, or if his tummy hurts or if his head hurts, but I think as your child grows you just grow with them and learn life in their own language.
He's going through a stage right now where he assigns numbers to things, even if they don't have numbers, and we have to remember that number 12 is French fries or number 50 is his kindle, or number 3 is Peppa Pig.
I agree with the PP above who said introduce as much AAC as you can, as early as you can. You can get some low tech AAC on amazon as a pre recorded push button system with symbols, and carry it everywhere. Model how it is should be used, use it when you need the toilet, need food, need a drink, need quiet etc.
I also think that with autistic children, TV can help a lot, especially if they're gestalt language processors. I can not recommend Yakka Dee and the twirlywoos enough for the repetition and use of language being modelled appropriately. They definitely helped us a lot with naming items and verbs.
