My son is 3yrs and 2 months and still can't really talk he can say about 10 words clearly,he will try to copy words I say to him but gthey don't sound anything like what they should.we go to a speech tharapist and as yet she says she isn't overly worried as he understands everything and will try to copy words.I was just wondering if there could be a reason for this and there could be some other problem causing him not to talk
