Hello, stutterer since I was 4 (accident). Support her no matter what, listen to her, let her speak at home without finishing the sentences. Just let her know she is accepted with all the issues she has. At school.. You cannot change many things, children are really mean sometimes, mainly because of their parents etc. Maybe you could talk with your daughter about some favourite thing to do after school or some school lessons program, where she can do something she loves and find some friends with the same passion. Many times stutterers like me thing too much about our issue but many people dont care. So maybe she can find some friends - because from my opinion, the most important is to let her feel she is part of something and she is great how she was created :)
