Stutter more with my dad with whom I've not lived with fulltime between ages 7-14 years of age. With my mum it's much more relaxed. Although I at times stutter with her I don't anticipate stuttering as much as I do with my dad. I'm mixed and have also noticed that I generally stammer more with those that are from the same country as my dad. When with them/dad I feel this "still small boy syndrome" if that makes sense.... I'm 44M.
