DS is 20 months and responds very well to his name but will never ever say it himself. We noticed this when we were chatting and saying to him 'Who is that?' and he'd name Daddy and Mummy and others but when we point to him and say 'What's your name?' or similar, he gets super-giggly and never wants to say.
The one time he did point to himself he then pulled a face like 'Oh you got me!'
I didn't think much of it until I spoke to a friend who has a two-year-old who does exactly the same.
Has anyone else come across this? Is it just a game?
