It sounds like the parent is talking about validation, not specific psychiatric action. I think it should be OK as long as they don't present their child as professionally diagnosed as such.

Thanks. We're only acting on it insofar as we read about it and try to find practical ways to deal with it. We're not going to medicate her! And when we discuss the topic, we always start with: "We believe that..."

It's not standard to medicate for autism, FYI. The standard recommendation is therapy (Applied Behavioral Analysis, occupational therapy, and speech therapy are most common). One benefit of a diagnosis is that often your insurance company will cover more therapy.

The right next step is to get an actual diagnosis, in my opinion. You might be off-base in your suspicions, or it may turn out that your child is more affected than you suspect.

Autistic people are routinely over-medicated, and that over medication one reason for the difference in life-span for autistic people.

After diagnosis? There are no drugs specifically indicated for treating ASD. You might find people on the spectrum getting prescribed ADHD meds, say, but I understand that's more of the exception nowadays.
