Three months ago I travelled with my wife to Ireland’s west coast for a reunion with our first foster placements, now settled with their new family. The two sisters, then aged five and two, had been removed by police from their home in pyjamas and driven to our house in 2017. I remember trawling around shops the next day, panic-buying clothes and pushchairs while my wife fed them, read to them, bathed them and administered nit treatments. The five-year-old stayed with us for two years. Her younger sister left us after a few months for another temporary foster family. Both now sail, ride horses, play rugby and are about to get Irish citizenship.
