Should I say something?

I have a friend whose kid clearly has autism. Her spouse also clearly has autism. I HATE to presume, but in this case it is so blatantly obvious that if it’s not autism, it’s surely some other neurodivergence that presents similarly.

I like this friend. I like the whole family. My usual rule is to keep out of other people’s business. In this case, her child is struggling with a lot of sensory issues, overstimulation, and my friend expresses being overwhelmed dealing with it all. I believe that informed support now could be a game changer and could set this child up for success.

Should I say anything? If so, how? I have said nothing yet. I’m not sure if I should. But I was so confused, frustrated, self-loathing, and felt alone until I was diagnosed at 18. I wish I had known earlier and had access to resources that would have helped me. I hate that autism is seen as something wrong or bad, so I can’t just say “hey your kid might be autistic” the same way you could say “maybe your kid needs glasses” or “maybe your kid has a strawberry allergy” yet here we are.

Edit to add: primary school aged child (between 5-10 years old). With access to therapy, meds, any other support, as needed.

Also, I would NEVER say “you are autistic” to anyone. I’m looking for a way to broach the subject as gently and respectfully as possible. I can admit I may be wrong. I have the nicest of intentions here. And I am not presuming anything. This situation made my Spidey sense tingle, but that’s not a quantifiable variable here. I promise I’m not an asshole and only trying to look out for my dear friend’s child.
