Des Moines Children's Museum is a non-profit with the mission to build the foundation of lifelong learning by promoting the power of play. Every Monday at the museum is Mask Up Monday. On Mondays we require masks for all visitors ages 3 and up to allow higher risk or more cautious individuals to visit the museum comfortably. Masks are optional the rest of the week, we ask that anyone unwilling or unable to wear a mask plan their visit for any day other than Monday.
