I have been photographing a mother and her two teenage daughters for three years--2011, 2012, and 2014--once a year in August, beginning when Rachel, the older sister, was 19 and Natalie, the younger one, was 11. I wanted to explore the complex developmental challenges facing all of them at this time of their lives: the need for both redefining their relationship and reinventing their individual identities. The primary question for the girls is "Who am I?" Who am I apart from my mother, apart from my sister, in my new identity as a woman? Their mother, who has perhaps been defined by her family and the girls' needs since they were born, is faced with similar questions: Who am I apart from my children? Who will I be when the nest is empty? With my children in their prime and me in in middle age, who am I as a woman?
