I am home educating my little girl with autism - not particularly through choice though - there are just no facilities in our LA until the specialist autism school is built next year. We tried school twice (first time mainstream, second time was an autistic unit in a mainstream) and it was a complete disaster for my daughter every single time.
If given a choice, I think I would do school part-time because I seriously need a break. I know school isn't meant to be respite, but unless your child has a life-threatening disease, you don't get respite....and I'm not sure any respite place would take my child anyway. Unfortunately, no school in our authority wants flexi-schooling....
We have a statement, but in our local authority, we do have a proper Elective Home Education Officer rather than an EWO and who does totally understand home education and is very supportive, although I understand this is rare.
The negative side for us is that I get no time - have to arrange a babysitter a week in advance just to go shopping....and spend a fortune on food deliveries on stuff I should just be able to get....As a 24 hour carer for a child with a sleep disorder of some sort, I am quite run down.
The positive side is that my child is coping a lot better, I don't have to sit around worrying and waiting for phone calls from school and her learning is a lot more positive because we are out and about in the community. We've met really great families at the local home education group and we can plan our life around our needs.
