It can really make a difference to ask them how you can help, whether or not they like it when you finish their sentences or if there’s any situations where they’d want you to talk for them. Being a person who stutters is tough and there’s a good chance that this kid is gonna have some bad experience that’ll make them think how they talk is bad. Sometimes when people around us treat our speech as the elephant in the room. That can make you feel, especially as a little kid, that stuttering must be horribly shameful and should never be brought up. What you can do be talk openly about their stuttering, how it’s okay and it’s not their fault. The fact that you care is so important. I’m glad this kid is going to grow up with such a good support system.
