I think SPD is more likely to be Diagnosed in boys, but that boys and girls are just as likely to inherit SPD from a parent.

My dad is oversensitive to the Universe, but never was diagnosed with anything.

Unless the SPD causes the girl to act out in negative (typically male dominated) behaviors, it is unlikely she will be diagnosed until she is much older.

In my case, I would just avoid the things that made me uncomfortable, but it only rarely caused me to act out. Since my sister has always been a monster, my few acts of rebellion (only willing to wear 100% cotton clothes) were mostly ignored as my personal quirks. Especially as my family was very "quirky".

I compensated for my visual and hearing based SPD problems by sitting in the front of the classroom and always paying attention to the teacher. I had to tune out the other kids or I couldn't "hear" or "see" the teacher. This was perceived as "Teacher Pet" behavior. For me, it was the only way I could figure out how to understand the material.
