Wild at Play

This Jersey City space was founded by parents' support group Downtown Babies, which began meeting five years ago. In the venue’s 2,300-square-foot playground, kids can slide, bounce, crawl and bump their way through a winding maze. The location also offers a range of classes (including music, dance and martial arts) and themed birthday-party packages. Admission for members only; see website for class schedule and additional membership details. Ages 3 months to 12 years.
