Every morning, Lisa Strong's 10-year-old son lifts her heavy prosthetic legs and screws them into the levers in her knees. He reaches for a pair of pants and pulls them up around her waist.
Then, at the bathroom mirror, her 11-year-old daughter gingerly wiggles into the space between her mother's arms, which are big and bulky and plastic, stiff like a mannequin's. The girl twists a tube of soft pink lipstick and glides it over her mother's lips.
"I cook, I clean, I do everything, I, mostly ... I brush her hair," Chloe Strong said. "When I was younger, I didn't understand. Now I understand completely."
