My mom stutters and out of me and my sister, im the one that got the stutter gene (I'm the baby) As long as you support your child and don't make them feel like shit, then you'll be good. It's been a lot easier since I've accepted my stutter. My mom is strangely "against" my stutter (as if I have a choice) and it kinda puts me down. But as long as you love them for who you are and encourage them that it's okay, then I think you'll be good
