You and Me Song

Our house is full of family photos. There's the small, scrunched baby, eyes tightly closed, his face full of thought, cuddled up to a small blue teddy in a hospital plastic fishtank cot. There's the nursery portrait of a toddler who's changed so much more in the months since it was taken. There's even a rare photo of the three of us on a Welsh beach last year. I have a double chin on this one, but there are so few pictures of Mummy, Daddy and boy that it made the cut. I just try not to look at it too much!

T is confused though. When looking at pictures of himself, he says 'you!'

Who's in the picture T?
(pointing) Mummy ... Daddy ... and YOU!
Well yes darling it is you, but you don't say you, you say 'me' ... look, I'm Mummy and in the picture that's me!
Yes, Mummy me, Daddy and youuuuuu.

I assume this is a learning process, part of T's complex language development, and will pass soon. Has anyone who has been there and done that got any advice?

On the plus side, I've realised why he was getting so cross when I opened yoghurt pots, fastened his shoes and carried his bag in response to the command 'you do it!'
