If you do decide to have a kid then at least the kid won’t be alone. They’ll have you and your mum who understands what it’s like to have a stutter. My own parents doesn’t understand and forces me to speak smoothly as if I can manually control my stutter. Your kid might suffer, but at least they’ll have you and your kid will end up being strong because they suffered too. But it’s up to you if you want a kid.
