My situation was similar. 3-4yr old chatterbox and then one day, bam, could barely say anything. My parents were great. They never made me feel bad, never tried to rush me and made sure I went to speech therapy. I can't say therapy helped me massively as a child, but it gave me a safe space with others who stammered and you didn't feel self-conscious for a few hours. I have siblings and thinking back, it was never mentioned. It's amazing to reflect on how great my family were at never making it into a 'thing'. The best quote about it that I was ever told was "It is something I do, it's not who I am". I went through school not being able to say my first or last name. I hated reading out loud in class. Fellow pupils laughed (they're kids, I couldn't blame them). However, when my teacher made fun of me in front of the whole class, that's where I drew the line. My mum was in school the next day to see the headmaster, whose daughter was in the same speech therapy class as me - big mistake!! He never did that again. Plenty of people have made me feel self-conscious about it - but you feel like that for a short time and get on with it. It's either because of their ignorance or cruelty and you can't control that. She could be made to feel self-conscious about her clothes, her car, her shoes etc etc, like anything. It's part of life, unfortunately and you can't be there to protect her for everything. My biggest problem is that I have always been talkative and like to tell jokes. However, this is made 10x harder when you can't get your words out. Frustrating! It never stopped me going for any job and I've had some jobs where talking to crowds is a must and can't be avoided. You just do it with confidence and if you stammer, you stammer. So what? Today - i just get on with it. I feel like I can sound odd when talking sometimes, as I falter on some words that are blocked, or I am quickly swapping words in my head so I dont stammer. When I am tired, I can barely get words out. But, overall, it's just part of what I do. Anyway - I suppose what I want to say is don't worry. She'll find her path but don't let it define who she is. It's just something she does. Don't make it into a big deal but give her the support she needs when she feels like speaking is just too hard that day. Her friends won't care, her employers won't care. She'll have good days and bad days, like anything. However, you sound like you're a very supportive parent and this will help massively.
