When I found out my 7 year old son thought Father Christmas wears a brown suit I was quite tearful. Now I know yours might think the same thing too and you probably don't realise it.
Did you know that your boy has a 1 in 12 chance (8%) of being colour blind BUT he won't have been tested for it in school (they haven't been able to afford testing for years)? His teachers are very unlikely to know anything about helping him (because they aren't trained in supporting colour blind kids). So YOU, his parent, are therefore the only one responsible for getting him tested, telling the school about it, checking he can see all the information in his textbooks and making sure he gets the help he needs for GCSE's, A levels etc. and of course, making life easier for him at home. Even your boy's nursery won't have a clue -just think how demoralising it can be to be colour blind in a nursery or primary school! To see how your son's world might appear have a look at www.colourblindawareness.org and please make sure you check out your boy as soon as you can.
I would love to hear from anyone who has experiences to share about the problems of being colour blind, especially in school. Girls have a 1 in 200 chance so don't forget to have your daughters tested too!
