Chicago Children's Museum has said they've got a dedicated nursing mothers room to help nursing moms have a better experience while visiting.
The museum stated:
"Amenities include nursing chairs throughout the museum, a nursing room, plentiful changing tables, including private family bathrooms, a bottle warmer (in the Pritzker Playspace), and other amenities that make the museum visit easy and enjoyable."
This nursing room also has electric outlets to connect your powered breast pump.
