Yeah i reckon it would be different for each child, we're expecting our 3rd and there is no way we could afford private for all 3 when they're all old enough but our oldest for example is so active that i think he would just get himself into trouble at a public school where the funding isn't there to give as much attention to individual needs. I really want for him to go to a private school. Its simply his personality that requires for him to have a bit more attention and to be in a very positive atmosphere. Our second child on the other hand is the sweetest little boy who i believe would be fine in a public school.
There are government 'special' schools for kids who are always in trouble, and when these kids go to these schools they have positive results because they are getting the extra attention and positive reinforcement they're personalities require. I want for #1 to get a positive start however and already be in that environment in a private school rather than wait for him to be labeled a troublemaker and be expelled from several public schools before getting the attention he needs.
