Is there an age when you have to accept that your child's never going to be independent?

[BigBird69]

Our son has learning difficulties following a stroke at birth. He is 9 but reading/writing/numeracy reception level. improvement this year has meant he can now recognise by sight a few three letter words. (Cat, dog etc) He is "talented" artistically and good with practical things, does not have social problems, he's not autistic, his IQ is deemed within the normal boundaries, but he has absolutely no concept of letters and numbers, dates, days of week, months of year.... Has anyone else had a eureka moment? Or should I start accepting that this is how it's going to be? I have always tried to remain positive but I'm not sure of I'm kidding myself.

Our daughter had pround learning difficulties from serious neglect ( now adopted by us) - out turning point was occupational therapy - you can get it on the national health but we paid a local practionet ( quite reasonable ) - and she came on in those areas in lesps and bounds. Ok shes 18 now and stillcant read a book but can read headlines in the newspaper , still cant add up or do
money - but there is some improvement little by little , We also had a special needs tutor and speech and language - please dont give up - the brick wall is a long way off
