I know this is pretty trivial, but I am concerned that DD will be cold in leggings or tights, but this is most of what we have and her little dresses look really cute. Trousers also tend to fall down a bit as DD doesn't have a waist really. Nursery always send her back with a couple more layers than I send her in, so I guess I am underdressing her. What do you put on your DD's legs?
