No such luck. Our third child was diagnosed with (mild) pdd-nos.
The good news is that she is already, at a little under 2 1/2 years only, further ahead in some areas that her sisters who are 2 years older (and her sisters are still relatively high functioning). She can talk and will use some small number of works appropriately, her social skills aren't that far behind where they should be, and her repetitive behaviors (if that's what they are) aren't too dysfunctional.
The bad news is that she is on the spectrum when we were really hoping that she was going to avoid it.
Autism really sucks.
