Thank you!! We try not to focus on it, apart from when we are going through the exercises his speech therapist has given us and of course we have explained that it is nothing for him to be ashamed of. We are just struggling with what to say to him to help him when he is being teased. I didn't know that Einstein and Lincoln had stammers. He is still a little young to understand their importance but at least I can say some very important and great people went through the same thing!
