Stanford maternity unit sets record with 4 sets of twins delivered in 32 hours

PALO ALTO, Calif. (KGO) -- Stanford doctors, nurses and parents have been very busy at Lucile Packard Children's Hospital in Palo Alto, welcoming a lot of babies.

Four sets of twins in just 32 hours, to be precise, according to the hospital.

The multiple twin marathon began on June 29.

Doctors delivered three sets of twins on that one day, and a fourth set the following afternoon.

The eight babies include Ethan and Yisol Lee, identical sisters Hadley & Olivia Sacher and brothers Henry & Logan Smith.

"I cannot recall so many twin births within that short of a time frame," said Lou Filoteo, RN, a nurse manager who has worked at Packard Children's Hospital for 19 years.

What are the chances? According to the hospital, the odds of having four sets in a row in such a short time are slim indeed: roughly one in 1,000,000.

Three of the twin sets are now settling in at home.

Identical sisters Hadley and Olivia Sacher, born weighing just 4 lb 7 oz and 3 lb 9 oz, remain in the hospital's intermediate care unit, where they are doing well, according to a hospital press release.
