Best of luck. Keep talking to him as he grows up - I think the biggest problem in my own childhood was not knowing how many options I had. If that approach is going well by age 4/5/11 I'd urge you to at least consider/talk about carrying on with that rather than sending him to school - I realise it's a huge commitment but I think I'd've been a lot happier that way (and my parents were apparently close to doing it but didn't feel up to it).
