my heart hurt as i looked at the pictures of them ; abraham at eight months old , teething on a green plastic stegosaurus he held with two hands up to his mouth ; benjamin , who lived a year longer than his twin , squatting on two chubby legs as he pushed a toy fire truck ; christopher , dead at two , shirtless in his picture as he stuck his tongue out at the camera ; david , his twin , three at his time of death , wearing a little suit , surrounded by ducks in a park ; ethan , four when he was placed into foster care , four and a half when he died ; and his twin , frederick , five when he died , four in the picture with ethan , their little arms around each other 's shoulders ; garrett , six , legs splayed out over the back of a shaggy , bored-looking pony , with his twin , henry , holding the halter .
