If it's any consolation. I was extremely worried about my 3 year boy inheriting my stutter. And he talks all day every day completely fluent. Children of people who stutter are more at risk of having a stutter but it's not a definite. Your stutter might not even be a genetic stutter and even if it is, Don't forget she's only got half your genes and probably even if she did get the gene that might have caused your stutter it might just increase the risk of a stutter it still could not manifest. The only thing you need to focus on about it is making sure if she does stutter you support her with it.
