The kindergarten class of 2015 increased by six, after staff at the Ohio State University Medical Center delivered sextuplets to a Columbus couple on Wednesday afternoon.
They were the first children born to Mia and Rozonno McGhee, 10TV News reported.
The couple had tried for five years to conceive, then got help through fertility drugs.

Rozonno McGhee watched as a staff of about 50 doctors, nurses and specialists delivered his four sons and two daughters.
"I can't believe this. I cannot believe this," Rozonno McGhee said. "This is so this is not real to me. I'm just happy I'm going to be a father for Father's Day."
As the babies were delivered, they were each given a letter. Doctors and nurses spent weeks practicing for the first-ever delivery of sextuplets in Columbus.
"We got them out, handed them to the waiting pediatrician with the appropriate letter," said OSU obstetrician Dr. David Colombo. "People had lines they walked. It was almost like the marching band. They crossed at the right places and there's not one mistake."
The babies weighed between 1.5 and 2 pounds each.
There was a seventh baby, a little girl, who was stillborn, 10TV News reported.
The surviving babies are expected to stay in the neonatal intensive care unit for three months.
