The Duke And Duchess Of Cambridge Depart The Lindo Wing With Their DaughterWilliam fondly recalls this moment, basically the last time Princess Charlotte slept.

When we met her on the steps of the Lindo Wing,
Princess Charlotte looked the picture of a sedate, quiet babe (as you may recall, she actually slept through the entire thing, an impressive feat when you’ve got the world’s media shouting and flashing cameras six feet away.) But now that she’s had time to rest up (being born is exhausting),
Princess Charlotte is less into the sleeping, more into keeping her royal parents awake all night.
