Hospital officials said the incident occured in September but the hospital is changing its procedures, according to the Pioneer Press.
The Pioneer Press said the mistake was discovered within an hour the family reunited with their child.
A baby's movement from the bassinet is logged everytime and the wristband is supposed to be double checked before a newborn can leave, according to, Mercy Chief Financial Officer Kerry Monson.
Monson wouldn't release details about the incident, nor identify the families involved.
Monson did read a statement about how "disheartened" the hospital emplotees are, the Bismarck Tribune reported.
