Quote from Shakespeare:

On Lammas-eve at night shall she be fourteen;
That shall she, marry: I remember it well.
'T is since the earthquake now eleven years;
And she was wean'd, I never shall forget it,
Of all the days of the year, upon that day;

Romeo and Juliet. Act I, Scene 3
(in other words, Juliet was three years old when she weaned)
