Comment was not aimed at you. Your doctor needs to determine whether it’s developmental or not. If it’s developmental then speech therapy will most likely fix it, and can grow out of it. But for myself, speech therapy did help, I met other children who also stuttered which made me realise I was not alone. We played games that involved syllables to help the flow of words. My therapist had a stutter as a child, but grew out of it later in life; she taught me how to grasp control by taking breaths before speaking, speaking slower to let it slide out, those kinds of things. For me, eye contact with the person I’m speaking to really really helps my flow. I don’t stutter when I sing and I don’t stutter 90% of the time when I speak to myself. I would say yes do take her to speech therapy as she will learn how to control it better and maybe meet other children who stutter. But for the most part, support her, don’t try finish her words for her unless she really is struggling (but ofc do if it’s due to age) and just reassure her that you are listening and make that eye contact.
