Here’s a wonderful kid-friendly list to share with your child about how dyslexia may affect them. By sharing these points, children feel heard and understood about how they struggle. In my experience, as soon as my daughter could identify things that were hard for her, she released the need to keep arguing about reading and spelling being so difficult as we understood what it was like for her. Once you identify things your child struggles with you can create a learning framework to work with dyslexia.
