Not sure if I will be much help and I really don't know what Turner's syndrome is. However, I was really worried about my daughters speech - she is 21 months - as she only says a few words clearly. Most only I can understand and they usually have first or last letters missing or are complete gobbldegook but because they relate to the same thing all the time, I know what they mean ( for example "Piglet" is pu and Eeyore is "Nnor"). I spoke to my GP, who used to work at the Children's Hospital and she said not to worry, they all develop at their own rate. She is also the mum of two young girls. She told me that the words don't have to be clear at this stage. I also spoke to my friend, a mum of four, who took her first to a speech patholigist at two and was told to just let him grow up. There was no problem in the long run.
I sometimes still worry particularly when we mix with other children who speak clearly, but I have had her hearing checked and look at her development in other ways and she is ok. Besides, she would not be able, at this age, to communicate with a specialist so I have resolved to watch her over the next twelve months to see how she progresses.
