Please please tell her right now at this young age **to be as confident as she can.** Tell her even if it takes stuttering through every single word or even screaming it in puplic(but obviosly not crazy, respectful loudness) , ***let her words be heard.*** **Right now what she needs to do is build confidence to the point where her brain completely disregards any type of embaressement.** Also shes young so its perfect, tell her when shes 16+ she wouldnt have cared what she would have done in the past and its much harder to build confidence as a teenager than a kid. Also when shes talking to you, please tell her to stutter on purpose and to not try to switch her words. Dont undermind her stutter. All the best
