Ds2 is a very happy chappy, but a soul of very few words. His only recognisable word is "mummy" (or memmy as he says it). He clearly understands us and can perform simple tasks like fetch his shoes, 'put it down' or 'give it to daddy' etc' He grunts to indicate he wants something and can usually make his needs understood, so I am not overly worried but it would be helpful to hear of other late speakers?
