She was diagnosed, they explain, with brain damage with unknown causes just after birth and has remained at the same developmental level since about three months. Three years ago she began to show early signs of puberty, and they grew anxious about the impact of fertility and of her rapidly increasing size and weight on the quality of her life. In discussions with doctors at Seattle Children's hospital they devised the treatment: removal of Ashley's uterus to prevent fertility, excision of early buds on her chest so that she would not develop breasts, and medication with high doses of oestrogen to limit her growth by prematurely fusing the growth plates of her bones. The parents insist that the treatment, carried out in 2004, was conceived for Ashley's benefit and not their own ease or convenience. With a lighter body and no breasts, Ashley will have fewer bed sores and lie more comfortably. And a smaller Ashley can be cared for and carried. "As a result we will continue to delight in holding her in our arms and Ashley will be moved and taken on trips more frequently instead of lying in her bed staring at TV or the ceiling all day long," they write. But as news about the treatment became known, Ashley's parents were surprised by the virulence of some of the response. Comments on chatboards have included: "Ouch - this smacks of eugenics"; "I find this offensive, truly a milestone in our convenience society"; "This smells, I can't agree with this".
