It's easier to educate a kid with stutter if their family already encountered this prob. Weakness can be counter attacked from very age of 3 or 4 and then the kid gets complete confidence to face the world. Strict parents won't make things better. Group reading and public/classroom exposure at very young age will relieve much of fear. Parents need to put good and continuous effort to make their kid very strong mentally between 3 to 7. These stuttering kids once resolved of all speech fear in these age will blossom and conquer whatever they wish. Remember kids at age can learn 5 languages. This is the right age to win the stuttering demons .
