Brooke weighs 16 pounds and is 30 inches tall. She doesn't speak, but she laughs when she is happy, and she clearly recognizes the people around her. She has three sisters: Emily, 22; Caitlin, 19; and Carly, 13. All three are bright, active and of normal size and development. They say that Brooke has ways of expressing herself like the teenager she is.
"She looks like a 6-month-old, but she kind of has a personality of a 16-year-old," Caitlin said. "Sometimes we joke about how she rebels."
Brooke will resist and refuse activities that don't appeal to her by vocalizing her displeasure, not with words, but with sounds typical of an infant. "She makes it known what she likes and what she doesn't like," sister Emily said.
Carly said it no longer seems strange to have an older sister who is still essentially an infant. "As I got older, she was just like another little sister to me," she said.
In her first six years, Brooke went through a series of medical emergencies from which she recovered, often without explanation. She survived surgery for seven perforated stomach ulcers. She suffered a brain seizure followed by what was diagnosed as a stroke that weeks later left no apparent damage.
At 4, she fell into a lethargy that caused her to sleep for 14 days. Then, doctors diagnosed a brain tumor, and the Greenbergs bought a casket for her.
"We were preparing for our child to die," Howard Greenberg said. "We were saying goodbye. And, then, we got a call that there was some change; that Brooke had opened her eyes and she was fine. There was no tumor. She overcomes every obstacle that is thrown her way."
Brooke's doctor said the source of her sudden illnesses remains a mystery.
"We often did not have a good explanation for why she became ill as quickly and intensely as she did," Pakula said. "There were many times in which there were real doubts about her ability to survive."
As she rocks back and forth in a baby swing, Brooke is fed through a tube inserted into her stomach, because her esophagus is so small that swallowed food could back up into her lungs and cause pneumonia.
Doctors recommended growth hormone therapy early in Brooke's life, but the treatment produced no results.
Howard Greenberg recalled the follow-up visit to the endocrinologist. "We took her back in six months, and the doctor looked at us and said, 'Why didn't you give Brooke the growth hormones?' And I said, 'We gave Brooke the growth hormones. We gave her everything you told us to do.' And Brooke didn't put on a pound, an ounce; she didn't grow an inch."
