How old is he?
My DD (ASD, ADHD, Dyspraxia and Dyslexia) had low level school refusal right from reception but when she started in year 3 it became very severe very quickly. We were battling during most of this time for an ADHD/ASD diagnosis with the local NHS Paed who was hopeless and failed DD terribly. Eventually we got to see a sensible Psychiatrist at CAMHS who took one look at her, diagnosed ADHD and told us he could fix her severe anxiety and school refusal with medication.
We had been very anti-medication prior to this point but were so desperate we decided to try it. It was an absolute life saver for DD and our family and the best thing we could have done.
Her anxiety and school refusal disappeared almost over night. Its not perfect, but we can manage her anxiety as it occurs and can now work with her to find solutions to particular causes or problems.
She has now caught up with her peer group academically and is absolutely thriving at school. She is enjoying her lessons and is very excited by the topics she is covering this term.
The medication allows her other therapies to work, as she can concentrate and understand what is being asked of her.
She is in control of her life when medicated. She understands what is expected of her both at school and home and can organise herself as a result.
There have been side effects though.
She lost over half a stone in weight at one point and like your son was very skinny to start with. However she has managed to regain the weight now and its much more stable.
She found getting to sleep difficult when she first started and each time the dose went up. However, as long as she has her medication every day, her sleep is fine now.
It has also made her ASD behaviors more obvious.
Deciding whether to medicate your child is a really difficult decision and not one to rush into. However its been a hugely positive experience for us.
maybe you could trial it and see if benefits outweigh the consequences?
