ST. CLOUD (AP) -It’s a personal record for this St. Cloud obstetrician who has been practicing medicine for 32 years.

Thirteen babies in 24 hours are all in a day’s work for Dr. David Kroska.

He calls it “spontaneous labor.” No twins or triplets were among the 13 infants he delivered in the 24 hours at CentraCare Clinic ending Friday, Sept. 13.

Kroska says he didn't realize he had delivered 13 babies.

Kroska says the mothers just kept delivering nonstop, including two cesarean sections. He says delivering babies is “still fun after all these years.”
