I don't know this woman, and I don't know what she is like, and maybe it is like you say. But your assumption that nothing is wrong with her daughter gives me a sick feeling.
Speech disorders and delays, as well as autism, can take many different forms. That her daughter can converse with adults and knows words to a few songs proves nothing. And sadly you cannot count on school districts for accurate assesment, or great services. In your journey with your son, you will need to become an Autism expert, as well as grow into a strong advocate. Networking with other parents and therapists will help you find the best programs and opportunities. School districts don't know a whole lot about Autism, and don't want to pay extra money for services.
If this woman's daughter "appeared" typical it doesn't surprise me that they didn't find a delay. There are many forms of speech and language disorders, many linked with Autism. My daughter is 7 and has an full autism diagnosis. She is verbal and social, and many might assume there is nothing the matter with her. She has something called echolalia. She memorizes speech (and movies, and songs). As a young child she fooled a lot of people, even therapists. These were just scripts, but the majority of people did not realize this.
We too had her evaluated by the school district as we made the transition from 0-3 services and even though she had been given many early intervention services (she also has mild cerebal palsy)they wouldn't qualify her for much. I seem to recall 10 minutes of OT a month. What a joke! She is going into 1st grade and even with intensive private therapy all these years, she still stuggles to hold a pencil to paper and form letters.
The speech therapy she needs is not just to learn words or articulation, but to learn what to say in certain situations. How do you get people to play with you at recess? What happens when you don't share with someone? How do people feel when you do this or that? After many years of therapy she has a lot more original speech. She is repeating and coping a lot less. For the first time I am beginning to hear her thoughts and ideas and feelings, and just not superficial speech. It's still new and awkward but it's starting. I am so proud of her! She has come so far!
It might seem strange but on a level I can relate to this woman. She might just be a crazy jerk - I have come across those too, but assuming that she genuinely feels something is wrong with her daughter. I can imagine her loss and frustration. She wants the best for her daughter as well. If she feels that there is something wrong, and mothers usually know, then maybe you should give her the benefit of the doubt. Maybe she is talking to you because she thinks you will understand what she is going through. I know how it is to listen to someone elses gripes and concerns about their kids and think, "that's nothing!". In time I think this might ease a little bit, but there is a lot of grieving that goes on following a diagnosis. No matter how much you suspected or expected it, nothing can prepare you for how you are going to feel when you hear those words. But please before you judge and make assumptions, know that there is a lot more to developmental disabilities than you probably know about at this stage.
I wish you the very best. This is not easy stuff, and it's really hard to let go of the dreams you had for your son. There is a really great essay called "Welcome to Holland". You may have already read it, but I just recently did and it was very helpful to me.
WELCOME TO HOLLAND

I am often asked to describe the experience of raising a child with a disability - to try to help people who have not shared that unique experience to understand it, to imagine how it would feel. It's like this......
When you're going to have a baby, it's like planning a fabulous vacation trip - to Italy. You buy a bunch of guide books and make your wonderful plans. The Coliseum. The Michelangelo David. The gondolas in Venice. You may learn some handy phrases in Italian. It's all very exciting.
After months of eager anticipation, the day finally arrives. You pack your bags and off you go. Several hours later, the plane lands. The stewardess comes in and says, "Welcome to Holland."
"Holland?!?" you say. "What do you mean Holland?? I signed up for Italy! I'm supposed to be in Italy. All my life I've dreamed of going to Italy."
But there's been a change in the flight plan. They've landed in Holland and there you must stay.
The important thing is that they haven't taken you to a horrible, disgusting, filthy place, full of pestilence, famine and disease. It's just a different place.
So you must go out and buy new guide books. And you must learn a whole new language. And you will meet a whole new group of people you would never have met.
It's just a different place. It's slower-paced than Italy, less flashy than Italy. But after you've been there for a while and you catch your breath, you look around.... and you begin to notice that Holland has windmills....and Holland has tulips. Holland even has Rembrandts.
But everyone you know is busy coming and going from Italy... and they're all bragging about what a wonderful time they had there. And for the rest of your life, you will say "Yes, that's where I was supposed to go. That's what I had planned."
And the pain of that will never, ever, ever, ever go away... because the loss of that dream is a very very significant loss.
But... if you spend your life mourning the fact that you didn't get to Italy, you may never be free to enjoy the very special, the very lovely things ... about Holland.
