Charlotte loves to put things into containers, then get them out again. And she will happily do this for long periods. On this visit I gave her a set of my discarded plant labels, and put them into a little straw handbag. At first she simply loaded and unloaded the labels from bag to table, doing this over and over. And she walked around with the handbag on her arm, in a distinctively queenly manner.
But intellectual exercise is very hard work. And so a girl needs a break for afternoon tea.
