Dyslexia is a hereditary condition, so if you have a history of dyslexia in your family, it's a good idea to get information now so that you can catch early warning signs in your own children. However, children today do not have to struggle as much with their dyslexia as the generations before them. We have a greater understanding of what it means to be dyslexic and we know which educational interventions are most effective in helping these children learn to read.
The Reading Rockets website is all about reading. Here are some articles on dyslexia that will help you identify signs and find help, so that even if your children are born with dyslexia, they will grow up to be readers!
Also, it is helpful to keep in mind the many overlooked strengths of people with dyslexia. Current research is focused on understanding how to interpret and foster these strengths. You can find out more in this article from the International Dyslexia Association.
