This week is Invisible Disabilities Week, and I wanted to share a little about my son, Lachie.
Lachie is 20 years old. He’s deaf, has level 2 autism, ADHD, type 1 diabetes, and PDA (pathological demand avoidance).
If you met Lachie, you probably wouldn’t realise he has these disabilities.
He’s independent, hardworking, incredibly organised and very capable.
At just 18 years old, Lachie bought his first home. He works, looks after himself, cooks, cleans and manages his own affairs.
He doesn’t do drugs, drink or smoke, and he’s probably more responsible than most people twice his age!
He also works for Mildura Disability Support Services as our systems coordinator, managing rostering and vehicles.
He’s a perfectionist, takes his responsibilities seriously and does an amazing job.
But beneath all of this, there are challenges people don’t always see.
One of Lachie’s biggest challenges is communication and socialising.
He finds it difficult to talk to people, particularly those he doesn’t know well. Starting conversations, knowing what to say and keeping them going don’t come naturally to him.
Making friends and building social connections is super difficult, even when he wants to. What seems like a simple conversation to someone else can take a great deal of effort for Lachie.
PDA is also widely misunderstood, or not known about at all.
It’s a profile associated with autism where everyday demands and expectations can create overwhelming anxiety and a strong need to maintain control.
For Lachie, this means that even something he wants to do, or is perfectly capable of doing, can become difficult when someone else asks or expects him to do it. It isn’t about being lazy, difficult or deliberately defiant. It’s about how his brain responds to demands and pressure.
Sometimes, the more he is pushed, the harder things become.
Giving him choices, allowing him to do things in his own time and respecting his need for independence can make an enormous difference.
That’s something I’ve learnt over the years. Just because someone is capable of doing something doesn’t mean they can always do it on demand, or in the way others expect.
I’m incredibly proud of the young man Lachie has become, not just because of what he’s achieved, but because of who he is.
One thing I always remind Lachie is, “I can handle whatever comes my way.”
And he continues to show me that he can, even when he needs to do things differently.
I think that’s something important to remember during Invisible Disabilities Week.
You can’t always see someone’s disability, and you certainly can’t judge their challenges or support needs by how successful or independent they appear.
Having a disability doesn’t mean someone can’t achieve amazing things.
Sometimes it just means they need to take a different path to get there.
I’m very proud to be Lachie’s mum. 💜
