There is a moment, every morning, when I look into my son's sleeping face and gently call his name. 'Good morning, pumpkin', I say, and watch his eyelids flutter and his face scrunch up at the sound of my voice. He stretches luxuriously and opens his eyes. A few seconds to focus, then his eyes light up and the most delicious smile of recognition spreads across his face.
It is a moment that obliterates the memory of the many sleepless hours that went before. That leaches away the tiredness from my bones. That fills the room with sunshine, no matter what the weather.
It is a moment that I savour, knowing that soon it will just be another fading memory of his babyhood.
But that is tomorrow - for today, this day, this moment is enough.
