There are lactation rooms available in the Capitol, Minnesota Senate Building, and the State Office Building.
Capitol - Room 104A is the Mother's Room. It is located on the first floor of the Capitol Building near the elevators/stairwell between the North and West corridors.
Minnesota Senate Building - Two rooms are available: G007 and G008. They are each labeled "Nursing Mother Room" and are located on the ground floor across from the double elevators.
State Office Building - One room is available. A key can be requested from House Human Resources on the first floor. During the legislative session the room is in high demand, so there may be a wait to access it.
