"We believe it's a personal decision," said Mary Beth Huber, director of programs for the Osteogenesis Imperfecta Foundation. "Many women who have bone deformity to the pelvis can carry a child and give birth."
The disability rights movement has empowered women who "a generation ago" would have never considered having a child, said Huber.
"Those with similar forms to Stacey might not have married or felt they didn't wish to have children or were afraid to have children," she said. "We know the risk of a Caesarian section delivery and respiratory problems are greater for mom and her baby, but we also know they can often be managed."
Despite his medical recommendations, even Dr. Tinkle is amazed by Herald's success so far.
"She feels like she can and will continue to do this," he said. "The medical advice is the odds are not a good outcome. But she has beaten the odds."
With the official verification from the Guinness World Records that she is the "smallest mother in the world," Herald said her story gives hope to other women who were told they could not have children.
"My children are my prizes," she said.
"I would tell those women, don't put limits on yourself, don't let people put limits on you, and for the grace of God, don't let anything stop you."
