Hi, thought I would join in with this thread too. I've been signing to DS for quite some time (when I remember to, that is) and he can do "hat" and "milk", but only when I prompt him/show him. I'm not sure he understands what it is he is doing though. I have been showing him "eat", "water", "more", "all done", "dog" and "bird" but I don't see him paying any attention. Do I just keep showing him those few signs until he gets them and can show me without prompting, or do I introduce more signs? I'm not sure if he is that interested in signing to be honest, but is it like that until they 'get it'?
