Vanishing twin syndrome

Vanishing twin syndrome is the explanation given for Fern Woolbright’s partial miscarriage: she has lost one baby, but a heartbeat remains, and the doctor concludes that she had been carrying fraternal twins. The condition makes the pregnancy a story of both loss and continuation, as one foetus disappears while the other continues to develop.

Diagnosis and explanation

The consultant explains that the evidence points to twins because Fern has lost a baby but a heartbeat can still be detected. In the case of fraternal twins, he says, two eggs have been fertilised and develop independently in the womb; a miscarriage can therefore affect only one of them. Usually the loss of a foetus is obvious, but sometimes it produces only bleeding like the bleeding Fern has experienced, while the healthy embryo absorbs the non-viable one.

Fern whispers the name vanishing twin syndrome before the doctor confirms it. His explanation gives clinical language to what has happened, but his description of the body as able to make things appear and disappear, followed by a finger-click and a laugh, renders the loss as if by magic. That lightness sits uneasily beside the fact that one baby has died.

Fern’s response and the pregnancy

The medical account briefly gives way to Fern’s own image of the twins. Looking at a drawing of two eggs and two non-identical babies, she imagines one resembling James Frobisher and the other looking exactly like Charlie Treadaway. This is her imagining, not a finding of the diagnosis; it places the abstract explanation of fraternal twins against the personal and emotionally charged figures through whom Fern pictures them. James tells her to listen to the doctor. She wants to protest that she is not a child, but recognises that the explanation matters.

Afterward, Fern spends the summer under her mother’s protective care. She is not allowed to ride, and Rosemarie Woolbright is even uneasy about her cycling the few miles into town. The weeks pass with check-ups and maternity clothes to buy, while Fern’s pregnancy continues. The syndrome thus marks a loss within an ongoing pregnancy: the vanished twin is named and medically explained, but the surviving baby remains the focus of the care and expectation that follow.
