health visitors and new parents sometimes fret when all they really need to do is wait. However, certainly where I live, the waiting list for a speech therapist assessment is about 11 months! They also routinely check hearing again if referred to a speech therapist, so dont' be alarmed if they send her an appointment for a hearing test anyway. My HV referred me to a speech therapist for my daughter as she said because the waiting list was so long, it would be sensible to refer now so that by the time the appointment comes along, if there is still a problem then it probably is a probably and I will have the appointment when I need it.
As it was, my daughter didn't really say any word until she was about 2 and half. SHe said a few half hearted words, but didn't gabble or baby chat or try to mimic words, she just sat and listened. Then when she did start to say a few words at 2 and 1/2, she progressed to full sentences within a few weeks and then was streets ahead with NO pronounciation issues and didn't even sound like a young child talking by a few month later. Now at age nearly 5 she is streets ahead in not only her diction but her vocabularly too than her peer group. My nephew who did lots of mimicing and spoke very early is a few month younger than her, but started speaking at about 18 months and still speaks like a baby and has a limited vocab.
At the end of the day, by the time children go to school, barring serious developmental problems, all children speak, are toilet trained and capable of most things by the time they go to school. Children do not develop to satisfy a chart of graph, they do things in their own time. Tell your daughter to try not to worry.
