There is a wide range of what mild autism can look like. I have one, my son is 7 and dx autistic spectrum disorder at 25m.
Chances are since she has some autistic traits you will be able to find a professional to say she is PDD.NOS, and you will be able to find a professional that says no she is not.
My father is asperger's. He is a 60 yr. old psychologist, married, father of 4. He was dx at age 35 when my brother was dx PDD.NOS. My father was dx as hyperlexic at age 3. There are many parents getting dx concurrently with there child. Liane Holliday Willey is an example.
My son looks like this. He has great humor. His eyecontact is good, but he avoids the camera (video, photo). His fine motor skills are a bit behind. He is particular about his clothing (no tags). He has an excellent memory, and is a backseat driver. He interrupts, sometimes has pressured speech (talks fast) and talks too loud. He is popular and has friends. Most of his friends are unusual. Sometimes he is excessively silly. He does not have a flat or blunted affect, and does not talk pedantically. Sometimes he answers in a nonsensical way. Sometimes he scripts and repeats verbatim lines from a movie/tv show. He has flight of ideas (changes topic). He is extremely good looking. He has a macrocephalic head, super recessive, green eyes (only 1-2% pop. has), he is very thin, and stature is between 25-50%tile. He is a bit immature with peers and doesn't always approach them in the most appropriate way. His girlfriend "Tessa" he used to kiss in kindergarten. After his teacher said, no kissing and was approached for a kiss by grandma he said, "Mrs Mosel says no kissing". We had to change that to no kissing friends, kissing family is ok. He is very literal. If I say we are going to run into walmart, he says, ah I think its safer to walk. He can get anxious and will wring his hands. He does not stand out from his peers. Sometimes he says awkward things. Like when reading the other day he said, "My heart is hurting from just sound-it-out". My son likes to wrestle, he craves deep pressure, he likes to be hugged. He has a broad range of interests, has never flapped. He is low muscle tone. His reading is at level, his writing is below. In school for schoolwork he is easily distracted, and needs to be told specific instructions to get started. Sometimes transitions for him are difficult. My son is very sensitive.
