My son had speech therapy, from 19 months old until almost 3 years old. He was simply delayed in speech.
They were from our local Early Childhood Intervention organization. Came to our house.
I called them myself. I did not have to get referred by our Pediatrician. It was free. Because it is for kids up until 3 years old.
ALL speech therapists, have different styles of working with the child.
But, they go according to YOUR child's, needs/situation.
It is not a generic template they use.
Your Daughter has JUST started speech therapy.
You need to give it time.
It is not instant.
It is not like 'something' is causing the speech delay. So don't expect that.
It is just development or motor skills. In my son's case. Or yes, IF there is a hearing problem, then that can cause it too. BUT, the child still needs to be worked with, per speech development.
Per the assessments they do on the child, they know what areas needs to be worked on.
In my son, he was just speech delayed. NOTHING 'causing' it. It is just developmental. But, in all other developmental areas, he was advanced.
He just took awhile to master speaking.
Einstein, did not talk until 3 years old. And he was a GENIUS.
Do not get impatient.
It is a process.
No kid, talks instantly.
My son had speech therapy 1 time per week for 1 hour.
The frequency of the sessions, depends on YOUR child's, condition.
Each child's schedule/session length and frequency, will vary.
Just ask the Speech Therapist, questions on this.
They should be able to tell you.
Not the Pediatrician.
The Speech Therapist is the one you ask.
In my son's case, the Speech Therapist does an OVERALL developmental assessment. Then based on that, they know what is 'wrong' with the child.
AND they then go over the assessment with the parent, and tell you of their findings. And how they work with the child.
In some cases, hearing problems may cause speech delays, or somethings like "Apraxia" or "Dysphagia." But again, the Speech Therapist, per their assessments, can evaluate this.
