Park Slope Armory YMCA
361 15th Street between Seventh and Eighth Avenues
Prospect Park YMCA
357 9th Street between Fifth and Sixth Avenues
Baby Boogie is $14 per child-adult pair; Story, Song & Shimmy is $12 per child-adult pair. Both classes are free for members.
The Baby Boogie and Story, Song & Shimmy parent and me classes are really marvelous. Boogie is for children up to 13 months, after which you graduate to Shimmy. The programs are run by enthusiastic staff members, who usually have a background in music, dance or acting. Activities including storytelling, singing, dancing, and frenzy-inducing add-ons, like the bubble machine. As well as being a fun forum where young kids can socialize, it's a great way to meet other local families. Find the schedules at the Park Slope Armory Y and Prospect Park Y websites.

Brooklyn Public Library Central Branch

You need good timing to get your hands on the coveted tickets for many of the library's free family events (consider arriving up to 40 minutes in advance!). This BPL branch offers Story Play, Babies & Books, and Toddler Time. The formats are fairly self-explanatory, but the kicker is the fantastic host: A sexy, middle-aged, Eastern European lady outfitted in tight leopard print clothes. You and your little darlings will love her! Check the calendar for the complete schedule. Read our extended review of the central branch of the Brooklyn Public Library.

Two Moon Art House & Cafe

When Perch Cafe closed its doors, Two Moon became the new home to sing-alongs hosted by popular local children's musicians Lloyd Miller of The Deedle Deedle Dees and Frank Gallo from Rolie Polie Guacamole. On Tuesdays at 10am, Lloyd strums his guitar and delights audiences with his original history songs and quirky humor. Visit Lloyd's blog for info on sing-alongs in other neighborhoods (he hosts six a week!). Frank, a renowned kids' entertainer in these parts, really rocks his slot on Wednesdays at 2:30pm, and Guacamole's percussionist, Ivan Katz, hosts a drum-along on Thursdays at 10am. All of these gatherings are held in the cafe's art gallery, a bright, airy space with colorful art on the walls and lots of natural light. Check the website for the complete schedule.
