My 27 month old is always always labelling things and it's important for her to know who owns what. In the morning "Mommy's coffee, my juice. Mommy's banana, my banana". My husband thinks this is a very odd quirk - is it, or is it just a standard phase ? And if so, please do tell me it doesn't last too long! I'm not particularly worried about it. But it does basically seem to be a road to focusing on what is "mine mine mine".
