Bush's letter begins saying they need some soft, blonde hair. As Barbara continues, she reaches the tough moment where he recalls that they had the daughter they needed.

"We need a girl. We had one once," Barbara read. "But she is still with us."

The letter continues remembering 3-year-old Robin, "We can't touch her and yet we can feel her."

Despite the fact that she is no longer present, Bush says he hopes she stays in their home for a long, long time.
