DD got diagnosed at 13, always a quirky 'little professor' but I put that down to being an only child. She is twice exceptional so academically gifted and autistic and the Ed Psych said her ability probably masked her disability at Primary.
She hates the secondary school environment, however I cannot fault the school or SENDCO who has been fantastic.
Noise cancelling headphones (Amazon, Anker Soundcore) have been a game changer as very sensitive to noise.
Time and patience are essential at home, managing energy levels with time to recharge, factoring this into weekends and holidays.
When I want DD to make a decision I'll give her an option between a couple of things much like I did when getting her dressed as a toddler.
DD has no challenging behaviour, shuts down rather than meltdown.
She hates small talk but will have very in-depth conversations with you. Will completely miss conversational cliff hangers.
Gets very frustrated with herself as she has high aspirations for herself and cannot always meet them. This weekend she had a match of her sport, her chest got tight during warm up (asthma) so she got really angry at herself, we sat in the car for a bit whilst she calmed down and she regulated enough to play the second half. We have worked with her coaches who have said from now on at away matches (where she has the biggest issues as unfamiliar etc) she will just do warm-up and second half and if she has to be subbed on and is happy to be will only play her normal position.
We went private 6 weeks from initial contact to having the report in my hand compared to 4+ years on NHS list, if you even make the cut which DD wouldn't have due to not having challenging behaviour. £2.3k our holiday fund but worth every penny. She also had the WISC V included which was possibly more useful as it showed her areas of strengths and weaknesses and the school have been able to implement strategies with this in mind.
If you are unsure between social anxiety and autism, in order to receive an autism diagnosis there has to have been signs from a young age (5 years ish and below).
