From early May through the end of October, there are going to be a lot of babies born at an Ohio hospital -- and that's just among staff members!

The baby boom is due to 11 labor and delivery nurses at Miami Valley Hospital in Dayton who are all pregnant. (Check out the picture of the 11 ladies showing off their baby bumps in the video below.)

The nurses joked with NBC 4 that pregnancy is not contagious, but said they are enjoying comparing notes about morning sickness and all the joys associated with pregnancy.

Six of the mothers know they are having boys, two are carrying girls, and three have yet to find out the sex of their babies.
