MISSOULA, Mont. - Community Medical Center in Missoula is seeing double this week.
The hospital is used to delivering babies, and it's not unusual to deliver twins.
Community usually records six to 10 sets of twins a year. But five sets in five days? That could be a record.
NBC Montana had the privilege of meeting two of the families who had twins.
Alivia and Nathan were born to Krista and Tony King. Tony is an identical twin himself.
The boy and girl twins started a trend when they came into the world on Monday.
Another set of twins, a boy and girl, were born the same day.
Then on Friday, there was a streak of twin births, 3 sets in one day. Four of the sets of twins are boy/girl teams. The last twins to be born Friday are little girls.
Allie and Dylan McFarland had a boy and girl. They named the boy Will, after his grandfather.
The McFarlands are asking NBC Montana viewers for suggestions on names for their baby girl.
If you have a favorite girl's name, go to the KECI Facebook page and let us know.
Lara Porrini is the registered nurse in labor and delivery who helped in three of the twin births.
Porrini went to high school with two of those couples back in Kalispell, including the McFarlands. She and both couples remain good friends.
"Flathead High has had a big day," said Porrini.
"I haven't heard of this many twins born in one week in the history of the hospital," said Community's OBGYN clinical manager Cindy Wolverton.
