I did consider homeschooling as dd's physical needs were quite difficult to fit around a school day. These were the main reasons that kept me off:
I know dh and I are quite quirky in many ways- good ways, perhaps, but quite limited. Also couldn't help noticing that many of the local
HE parents were also quite like us. I thought it might be better for dc to experience some more "normal" families too. In retrospect, I think for ds being able to make friends from families who were less academic, less middle-class, less arty has been his salvation: he is none of those things and much as he loves us he would have thought of himself as a misfit.
In our area, quite a few of the HE activities and meet-ups
would require use of a car, and even if I had been able to drive, I was always quite strongly against unnecessary car use. It seemed to me that by keeping them in school I was able to access a hub of activities and different people without those journeys.
Dd was very clingy and very inclined to trust me in everything. Remembering how much I admired my own parents and how long it took me (even without HE) to learn to have my own opinions and question theirs, and how this has not always been helpful to me in life,
I wanted counter-weights in her life.
Dd herself wanted to go to school, even at times when life was most difficult.
Having said this, I am also convinced that my friend who HE'd her son made absolutely the right decision- for him. He was autistic, didn't cause any trouble at school, but simply did not socialise or learn anything, he was just passing through which is a dreadful waste of a young person's life. By a judicious mix of HE and social activities, she encouraged him to learn, she helped him to build a friendship circle, she gave him an interesting life.
I never listened to her when she told me to HE dd, but otoh I never doubted that she had made the right decision for her ds.
