Despite the cool temperatures, believe it or not, spring has truly sprung! If you've got little ones who are itching to get out and enjoy the season, you're in luck: we've got a list of some of the best things to do with the under-5 set this spring. When the sun makes an appearance, get outside with your kiddo for a nature walk, Earth Day celebration, and Fairy and Pirate Festival. April showers are the perfect excuse to head inside for preschool-friendly performances of Peppa Pig’s Big Splash, Sesame Street Live, Cinderella, and The Lion King Jr. If you're up for a day trip, the season openings of Sesame Place and The Land of Make Believe are worth the travel time.

Percy Jackson fans rejoice: The Lightning Thief: The Percy Jackson Musical has returned to the Lucille Lortel Theatre in Greenwich Village. You don't have to have read the books to enjoy this full-length musical production, though my son and I adore the Percy Jackson and the Olympians series by Rick Riordan. We were disappointed we missed the Theatreworks hourlong production in 2014, so when we heard it was expanded and heading back to the stage we knew we had to check it out.

With amazing talent, catchy pop-rock songs, heaps of humor, and a storyline with themes kids can relate to, demigod or mere mortal, it's a must-see for fans, according to my 13-year-old son.

Got energetic kids who are bouncing off the walls at home? Head over the new Launch Trampoline Park in Deptford, where bouncing off walls is highly encouraged!

I recently went to the grand opening weekend with my 3- and 5-year-old boys and had a blast. There is a lot to do, and unlike your average bounce house or indoor playspace, adults can jump right in and participate without feeling out of place.

Here's what you need to know before you go.

Therapeutic meets functionality at the newly opened Sensory Beans children's gym in Wantagh. Designed for children with sensory and special needs, the open-play space offers a vibrant and engaging world of visual and tactile stimulation. It is a family-facilitated gym for Long Island children of all ages and abilities. 

Here’s the scoop on the latest ice cream trend: There is no scoop. If you’re looking for something other than your typical ice cream shop this spring and summer, take the kids to try ice cream rolls. Rolled ice cream started in Thailand and, lucky for us, many shops have opened right here in New York City.

When we heard a 12-foot high outdoor climbing wall had landed on the waterfront in Brooklyn Bridge Park, my tree-climbing, monkey-bar-swinging son had to give it a try. As longtime Brooklynites, we’ve been taking advantage of the ever-expanding Brooklyn Bridge Park and great Dumbo eats for years. The addition of Dumbo Boulders offers yet another great reason to visit the neighborhood.

This is the second post in our new series about why it's great to be a mom in different towns around the Hub. Got pride in your 'hood? Let us know at boston@mommypoppins.com and your town could be featured in a future post.

We know, we know...Swellesley has a reputation for maybe being a little too pleased with itself already. But when we moved here with two small kids (and one on the way) six years ago, we found out that this town—which celebrates its 136th birthday today!—has a lot to be proud of beyond all the manicured lawns and nails. Great green spaces and terrific local businesspeople make this community one of the warmest and friendliest places we've ever lived in. Here’s just a sampling of what we’re grateful for—with what’s worth checking out when you swing through the ‘burb.

LEGOland Discovery Center at Plymouth Meeting has been building up to be the destination for every nearby LEGO-loving kid. From 9-foot tall replicas of city landmarks, to a 4D cinema, Ninjago training camp, and more, brick lovers from all over are excited about this brand-new attraction. My almost 5-year-old daughters have asked to go back multiple times a day, every day since we visited.
