You are so lucky you don't have to worry about it anymore, even when you still stutter. Thanks to your supportive father. My parents didn't care if I stuttered. They were better things to think about having to cater for 7 other siblings in an environment where resources were very scarce. I am still struggling with it in my forties. And my 3 year old seems to have it too. But I believe it's a child thing and he will definitely snap out if it.
