I think it’s possible she has a stutter, but I think the best thing you can do as a parent is IGNORE it and just pretend it isn’t happening. Respond to the content of her speech, and not how it is said. Do NOT under ANY circumstances make her feel that there is something wrong with how she speaks. The most important thing is that she feels loved, appreciated for who she is, and able to freely express herself. I would not involve an SLP at all until she shows signs that her speech is distressing her in a major way. If her speech is never distressing to her — which hopefully it won’t be if she has parents who joyfully listen to her express herself with no criticism — then you need never involve an SLP at all.
