Why COSI why was this picked

COSI's little kidspace is designed and staffed by early education experts for children from birth through first grade. Inside are a tree house, a health clinic with a pretend ambulance, a light and shadow workshop, a farm-to-table area and a water play zone with wheels, bells and ramps. A private nursing room and family restrooms sit alongside, and older siblings up to age 11 use the separate Big KidLab. Online general admission is $25 for ages 2 to 12 and $30 for ages 13 and up, and children under 2 enter free.
