Hi My 22mth old hardly says anything not even mum and dad all that often - his favourite word is 'Whose that' - he makes all the baby talk but no actual words and my mum and everyone keeps saying he should be talking by now and saying things like Ta/ Mum /Dad/ Nan/ Hi ya/ Drink - should I be worried as I am fed up with everyone saying is he talking yet. In other areas he is very bright and understands everything you tell him to do etc - Also when I get Bounty mailings they say he should have a vocabularly of about 200 words? I have also noticed he keeps biting his hand and leaving marks which I put down to frustration - Please help do I need to worry as I called my HV and she said to worry about 2.5yrs
