It’s not something you can teach someone you definitely didn’t pick it up at daycare. My husband has a stutter (i came to this sub because my toddler daughter started speaking with one and we were looking for some early childhood resources) and he was so worried about it, but in my experience it doesn’t work like that. I don’t think kids “hear” it until they get older, like the way kids don’t realize one parent has an accent until someone points it out. I had a friend in HS whose dad has a stutter who didn’t realize until middle school when a friend said something. I think when you grow up hearing it your brain doesn’t process it the way other people do. No research on that, just a theory. But regardless, your child won’t learn it but might inherit it.
