Children's Museum, located in the historic Lafayette neighborhood between Denver and Boulder, creates a highly safe exploratory space specifically for infants, toddlers, and preschoolers. This weekend features a 'Little Engineers and Pneumatic Experiments' themed workshop, where children can launch homemade parachutes in wind tunnels, operate magnetic gear walls, and build miniature dams at water flow experiment tables. A dedicated Toddler Beach padded crawling area is covered with fall-protection mats for babies aged 0-3 to crawl and engage in sensory exploration. The entire museum is a single-story design with no steps, making stroller access to exhibits very convenient. Restrooms are specially equipped with child-sized toilets and step stools, and diaper changing stations thoughtfully include cleaning wipes. A dedicated quiet nursing room is available, featuring gentle eye-friendly lighting and soft nursing chairs. Convenient free street parking is available in the surrounding neighborhood. ## Similar picks coming up in Denver - [Play-Well Winter Wonderland Workshop using LEGO Materials](https://grassyknees.com/denver/activities/play-well-winter-wonderland-workshop-using-lego-materials--listing-ed82a2a4240d1773b545069b) — Sat, Dec 5 · 12:00 PM – 1:30 PM · Baker Community Center · From $32 · checked Oct 16.
