Twin preemies share a bed in test of faster weight gain
NCT ID NCT01480856
First seen Sep 14, 2026 · Last updated Sep 15, 2026 · Updated 1 time
Summary
Researchers are testing whether placing preterm twins together in one bed, called cobedding, helps them gain weight faster than keeping them in separate beds. The study includes 64 twins born between 30 and 34 weeks of gestation who are cared for in a neonatal intensive care unit. Beyond daily weight gain, the team tracks breathing stability, body temperature, comfort, when intravenous feeding can stop, and how parents are doing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cobedding, placing newborn twins together in a single bed
- What this could lead to
- If cobedding helps preterm twins gain weight faster and stay more stable, hospitals could adopt it as a simple, low-cost part of newborn intensive care.
- What could go wrong
- This is a small study of 64 twins born at 30 to 34 weeks, so results may not apply to all premature babies. Cobedding could also raise safety concerns if one twin's condition needs separate monitoring.
