This portrait of my son, by his bedroom window, started as a simple exercise to capture his likeness at an age when he is still prepared to humour me, just. As such, it is an unremarkable addition to the long-standing tradition of mothers painting their children. I was unprepared for my emotions as I painted. So very different from taking yet another casual photograph. Each feature was familiar, yet the more I looked the less certain I was of what – or whom – I was seeing. The visceral memory of life within me, now transformed into a full person, wholly separate and individual. It took me aback. I think I know him now but I cannot be certain. What is beneath the surface? Who will he become? Painted before the COVID-19 lockdown, now a picture of a child staying indoors by his bedroom window takes on a broader significance. How will this experience change us? We are behind our curtains, forced inward. Who will we become? Who will you become?
