Slime in the carpet. Glitter on the walls. Paint on a brand new couch. These are just a few of the art-projects-gone-wild I've cleaned up over the years. And though I know the value in all this messy fun and creativity, sometimes I just don't want to deal with stocking the supplies, guiding the activities, and cleaning it all up. Enter the Children's Museum of the Arts. For my money (and sanity!) nothing beats a trip to this creative hub. Dubbed by my arts-loving daughters as their favorite NYC museum, it's an arts education powerhouse that doubles as an indoor playspace, making it a must-visit for NYC guests and tried-and-true boredom buster for city parents.

Harry Potter fans, grab your brooms: The long-awaited Harry Potter: A History of Magic exhibition is now open at the New-York Historical Society, with plenty of magical lore, historical artifacts, original manuscripts and drawings, and family-friendly programming to rekindle your love affair with the blockbuster books in whole new way.

On view now, the exhibition runs through Sunday, January 27, 2019, and timed admission tickets are selling out faster than a Fizzing Whizbee. Read on for a peek inside the much-anticipated exhibit.

Everyone loves a parade, but there's nothing quite like a neighborhood Halloween parade. While families with older kids may venture out to the iconic Village Halloween Parade on Sixth Avenue in Manhattan, it can be pretty scary—it's always insanely crowded and loud, and many of the costumes are risque, gory, or in poor taste. If your children aren't up for that big Hallow-baloo, there are plenty of smaller, kid-friendly NYC neighborhood parades in Manhattan, Brooklyn, Queens, and the Bronx, including the Ragamuffin Parade in Bay Ridge, the mega Jackson Heights parade, the famed Park Slope march, and a G-rated Village parade for little ones.

We've rounded up community-driven Halloween processions for families to watch or march in, most of which are FREE. If you don't live in a great trick-or-treating area, these parades are a wonderful way to hunt for candy in another neighborhood. Find even more seasonal happenings in our Halloween Fun Guide.

What's the one way to make a costume-and-candy-filled Halloween celebration even sweeter? Make it FREE. In New York City there are so many no-cost Halloween celebrations, we've decided to give parents a real treat: a roundup of FREE Halloween events for kids in all five boroughs, including big annual family favorites like Fort Greene's BAMboo! block party, the Halloween Parade and Pumpkin Flotilla in Central Park, and more.

So bring your trick-or-treat bags, but leave your wallets at home for these gratis happenings, and then check out our Halloween Fun Guide for details on the best costume parades, trick-or-treat spots, and other seasonal activities.

New York City doesn't lack for fabulous museums or Instagrammable-popups but put them together and you'll come close to the brand new Museum of Illusions, opening today in Chelsea.

Equal parts trippy, mind-bending fun house and educational wonderland, the museum is home to more than 70 exhibits that will trick your senses, force you to question your perceptions and look at the whole space from a different perspective. Modeled after the original location in Zagreb, Croatia, the New York location is the first installation of its kind in the Western Hemisphere.

The maker movement is alive and well in NYC, annually bringing one of our favorite festivals, Maker Faire, to the New York Hall of Science.

But what to do with your inventive child the other 51 weekends of the year? Of course there are after-school classes, birthday parties, and summer camp options, but for drop-in, one-off workshops and tinkering sessions? Not as many. Still, we've dug in and rounded up nine NYC maker spaces offering chances for year-round STEM-inspired making, building, and creating, from robots to 3D printing and creative coding.

If you're looking for a longer-term commitment, check out our STEM Guide to read up on all the options for maker-inspired camps, classes, and DIY fun.

New York City doesn't lack for spectacular destination playgrounds, but Hippo Playground is more than a great place to play. Nestled among honey locust trees and a stone's throw away from the Hudson River in Riverside Park, Hippo Playground serves as the heart of the community for this slice of the Upper West Side and countless tots have grown up playing in the cool shade of its trees.

What the Hippo Playground may lack in modern bells and whistles, it makes up for in community and character, starting with the playful pachyderms who form the centerpiece of the playspace.
