I’ve got a stutter and I’ve said to myself for a couple years now that I wouldn’t have kids (I’d adopt or use a doner though etc). Half my family have one but I’m by far the worst. What I’ve realized is that I’m probably this way because of lack of support I had/have from my parents. They never spoke to me about my stutter, always ignored talking about it. At the same time, I was very protected and they would talk for me in restaurants and stuff. Now looking back, I don’t think that added any benefits. My dad has been pushy about me doing a speech course and my stepdad always says ‘relax’ when I stutter. So once again, not saying the right things and making me more anxious (unintentionally though). What I’m saying, is that I think that I don’t think he should worry about your kids having a stutter too as long as you both try your best to get them to embrace it. Theres also a chance that they won’t have a stutter at all
