Thanks everyone
It is mainly his speech that I am concerned about although i do sometimes have concerns about his understanding.
It's hard to explain but I would say that the majoirty of words he says can only be understood by me, and sometimes his sisters (i.e those who are used to them). When saying some words, he seems to make completely the wrong word sound or he seems to miss the beginning and end of the word sound off. Trying to think of an example. I mean he can sing the bob the builder theme song, and you would know it was that from the tune but almost all of the words are non recognisable as words, ther same with twinkle twinkle little star.
For the past 2 days he has been telling me something and i hadn't the faintest idea what he was on about, turns out he was saying high 5 (he wanted the dvd on), now it sounded nothing at all like high 5, not even close.
He can say quite a few single words, like mom, dad, car, lorry, asda, walk, etc etc, but again most of them are only understood by me.
He spoke to my dad on the phone the other week and my dad didn't understand a single word he said, i however understood the lot because i know what he means.
I don't know , maybe i am getting worked up about nothing but i'm sure that at 2.3 he should be speaking more clearly than he is.
As far as his hearing goes, I am just not sure. I was surprised that he failed the test, but i was in the room and he really didn't have a clue when the noise sounded some of the time. Also the fact that he keeps making me turn the tv up isn't good.
Thanks for that link Jimjams, am gonna have a look now.
