My youngest daughter has all manner of problems with social cues.
She also has the condition where she does not see faces.
That is not what it is exactly, but since I am not familiar with the technical terms, I do not know how better to describe it.
Uh oh. Has she been tested for autism?
In the past, it was assumed to be a condition that affects boys only, and often went undiagnosed in females. But recently it has been found that they can be equally affected, they just tend to mask it better and the symptoms may manifest differently.
And instead of autism, we now tend to call it ASD, Autism Spectrum Disorder, because there's a whole lot of traits that may or may not be present in one person. I got away with a light form, I just have a few traits and not too extreme, but it still affects me.
It cannot be healed - our brains are just wired differently. But if you know what you're dealing with, you can consciously employ coping strategies, because this world ist not built to our convenience.
So I would suggest to have your daughter tested. It doesn't need to disrupt your lives, it can just give you a few answers and some tricks how to cope.
Btw.
