My son is 3 1/2 and is apparently due to start school this September (when he will just be 4) He has a mental age of 12 - 18 months and I feel that school is just not an option at the moment, despite reassurances that everything will be tailored to his needs. I would rather he attended a nursery, prefereably mainstream, to enable him to interact with 'normal' kids on his intellectual level. Any ideas/information/experience would be gratefully received!
