My 4 year old doesn't talk in sentences
I am very worried about my 4 year old son (he will be 4 in 4weeks). He can name anything u ask him, but he doesn't speak in sentences. When he was 2 and a half he started counting from 0 to 10 and he was counting down from 10 till 0. He also knew all his shapes even the hard ones like hexigon and pentagon and octagon. I wasn't worried then I seriously thought he was smart. 2 years later he's still no talking in sentences, when he wants something he simply says water or eat.
He used to watch a lot of Tv and he only seemed to response to Micky mouse. He can sing all the nursery rhymes perfectly.
He interacts with his peers fine, he plays with his brother also fine.
He was seen by specialists 3 months ago, and all they said was that they wanted to see him in 6 months time.
He had his hearing tested and it was fine.
At the moment I don't know what to do can anyone please help!
