Two pink lines on a pregnancy test. The primal scream of a woman pushing through her thirty-fifth hour of labor. The moment a still-wet newborn is placed in his mother's open arms after an unexpected C-section. The bottomless love reflected in the eyes of a father seeing his daughter for the first time. The moment a baby latches on to her mother's breast. Or the moment that mother decides to switch to formula. Each of these, and so many more, are stories of entering motherhood. Motherhood is an identity, a calling, a battle, a journey. By sharing their experiences, the contributors offer an informative and deeply affecting account of what it feels like when a woman first realizes she is a mother. This beautiful collection features essays by: Christy Turlington Burns, Emily Oster, Emma Hansen, Rachel Feinstein, Ashley Graham, Sienna Miller, Katrina Yoder, Amy Schumer and more.
