My little boy is 4 in March and his speech is not as good as his peer's. I can completely understand what he's saying, but their are letters and sounds he can't say - 's' and 'th' and 'z' and 'y'.
He's had a hearing test (which was fine) and now I'm trying to sort out some speech therapy.
Has anyone else had experience of this? And how quickly did they improve?
Thank you.
