The crib and changing table are still in the baby’s room, empty and untouched since Lieutenant Commander Kristin Bowen and her husband, Lieutenant Joe Turnbull, assembled them more than a year ago. Inside the closet that she painted pink, a collection of yellow and blue dresses remain on hangers organized by wooden placards: 0-3 months, 3-6 months, 6-9 months . Tiny shoes overflow a bin on the shelf above. Striped, floral, and polka-dotted headbands with bows dangle over hooks on the wall.
