Claiming to be the second-oldest children’s museum in the U.S., the Boston Children’s Museum looks more like it could be the newest. Credit the recent $47-million renovation that’s transformed a former wool warehouse into an adventurous, interactive getaway for kids. There’s room to paint, climb, build, jump, sing, and explore — and don’t worry, adults fit right in, too. Everything is geared to the 7-and-under set, with a special “PlaySpace” for kids under 3. On Fridays between 5 and 9 p.m. admission for everyone is only $1. Add to the fun by arriving on an MBTA commuter boat; the museum is but a short walk from the Long Wharf/Aquarium drop-off.
