From the Field Museum's entry in the hall of fame

With two large family-friendly restrooms on the ground floor, the Field Museum features sufficient stalls and sinks, as well as eco-friendly hand-dryers. The women's restroom has a special nursing room with a shut door, sink, and small sofa for new mothers. The women's restroom also has a large Tot Area with smaller toilets for our littlest guests. The restrooms are also right across a Nanny Caddy filled with diapers, band-aids, wipes, etc.
