Clemency and me on the medieval bridge at Hospital de Orbigo, on the Camino Frances. I’m trying to find my earliest memory of her. I think I have it. It’s 1968, so I am 15 and she is only a few weeks old. The shop is busy, so I’m left, literally, holding the baby, not that I mind or anything. Far from it. Very far from it. I proceed as Mum has shown me. I measure out the formula and mix it and place the bottle in a bowl of boiled water to heat. I test the temperature of the milk by splashing a few drops on the inside of my forearm, then hold her in the crook of my left arm with the bottle in my right. I put the teat between her lips and watch how her suckling makes her tiny cheeks move. She opens her eyes and looks vaguely around, the way new babies do, then her eyes catch mine and she looks up at me. Her eyes are so blue. In all my life I have never seen anything quite so beautiful. She coughs and gasps on the milk, so I stand, and lift her onto my shoulder, and pat her back....
