My 21 month old DD is a right chatterbox and seems to be picking up new language all the time. This last couple of weeks she is using lots of pronouns - you, me, us, hers, his.
But she uses "you" to refer to herself (since I guess we use "you" to refer to her!) and will use "me" to refer to me. It's all very logical, but I don't know if using them properly is just something she'll pick up in time or if I should try to explain - and how on earth to explain that she is "me" to herself and I am "you" to her?!
