Streb the School
51 North 1st Street between Kent and Wythe Avenues
If your kids want to run away and join the circus, they need to stop here first. Founded by choreographer Elizabeth Streb, who's known as the "Evel Knievel of dance," Streb offers classes for adults and kids in movement, acrobatics and aerial arts. In the Kid Action program, students are encouraged to test their limits by exploring impact, velocity and the defiance of gravity by trying cool stunts and dabbling in acrobatics. In Kid Fly, participants learn how to swing on the flying trapeze. There are also more specialized offerings aimed at specific ages like Baby Action and Teen Action, as well as Trampoline, German Wheel and Kid Action Combat, where kids become mini stuntmen.

Klub4Kidz
159 North 4th Street
When it first opened in 2010, we were wowed by this state-of-the-art kiddie gym, which offers drop-in play as well as memberships for regulars. Now, K4K has launched a series of pop-in art, science and athletics classes for little kids on select weekdays. Drop-off play is also offered.

Twinkle Playspace
144 Frost Street between Graham and Manhattan Avenues
We also raved about this drop-in play space for ages 0 to 6 when it opened in 2013. Owned and operated by a longtime local Brooklyn family, this one-of-a-kind, 4,500-square-foot tot spot features creative custom-designed hands-on activity stations, including a water table, a firehouse, a salon, a general store and a barnyard. A great option for preschoolers who love to pretend. Party packages and classes are also offered. Find prices on the website.

Frolic!
Sadly this venue closed in September 2014.
Another stunning indoor play space, Frolic! unfortunately doesn't offer open play in its rock-and-roll-themed gym. However, memberships are available and there are a wide variety of classes for preschoolers, including art, soccer, dance, cooking, Spanish by Bilingual Birdies, and its signature offering, Little Rock-its, a music class created by Tim Kubart of the upbeat kids' band Tim and the Space Cadets.

Baked in Brooklyn
242 Wythe Avenue near North 3rd Street

At this textile spot, kids can learn to sew (with or without a machine), weave, knit, embroider and crochet, so you know grandma will be proud. Kids can drop in to a one-hour session or buy a ten-class pack. First-time visitors can download a coupon for a free trial class on the website.

Music for Aardvarks
Mini Jake, 178 North 9th Street
Mini Jake, the hip Williamsburg children's boutique, hosts Music for Aardvarks classes taught by popular kids' crooner AudraRox. The Aardvarks program is a personal favorite of mine: My daughter loves David Weinstone's interactive original songs and I'm happy to hear tunes besides the usual nursery rhymes.
