Acknowledge the problem with your child:
Talk about it, but in a positive way. Say things like: "Yes we have a problem, but the best thing to do, is to do something about it."
Make a new start:
Wipe the slate clean and say "Let's put the past aside. We're going to teach you to read in a very special way, that's just right for you." Make a commitment and stick to it.
The approach must open the door for success:
Take very small steps. it is essential for your child to experience success. Praise the smallest thing, one step at a time. Start with something the child is interested in to motivate them and make learning seem fun.
Establish a routine:
Set aside a special time for the both of you to sit down and focus on the child. Be open to their learning style - some children learn better when things are written down or drawn in pictures. Brief, frequent sessions will work best, especially at the start.
Show them that you expect this to work:
They will take cues from your confidence, so make sure they see you being just that. Celebrate each step forward with them.
Use the child's strengths:
Their own language, their interests, their current knowledge - it's familiar territory and far away from word lists, charts and books that label a person a non-reader. Use this, be committed and you will succeed.
