Well almost 2 months after receiving mine for dd I can categorically tell you it does!
The worst part for me was the unknown and knowing that she had something that no body else agreed with. It was actually far more damaging than knowing.
I feel so much more confident as a mum and happier to say asd rather than her asd traits.
As I am now less anxious I am a better mum and all round we are much happier.
To have a reason to explain why your child behaves they do is so helpful and I just feel it has helped all of my family immensely.
