New York City may have the Lego Store in Rockefeller Center, but if your kids are as obsessed with Legos as my eight-year-old son, it's worth taking a trip north to the brand-new Legoland Discovery Center, which opened a few weeks back in nearby Yonkers. When we set out to visit over spring break, I worried that it would just be a glorified Lego Store and not worth the schlep to Westchester's Ridge Hill mall. But I'm happy to report that the Legoland Discovery Center is a super-fun play space that has a lot more to offer than just building ith Legos.

The only Legoland Discovery Center on the entire East Coast, this new family attraction offers hours of indoor fun, including rides, interactive stations and a massive play structure to explore. Your kids don't need to be Lego nuts to enjoy themselves here: Even though there were literally hundreds of thousands of Lego pieces at my son's disposal, he didn't stick one pair of plastic bricks together during our visit. He figured why waste time on something he could do at home when there were so many unique Legoland Discovery Center experiences to try.

Of course as cool as the new Legoland Discovery Center is, there are some important things to know before you go to help you make the most of your visit. So here are my top 15 things to do at Westchester's Legoland Discovery Center as well as my insider tips as a mom who's been there, done that.

While spring brings outdoor festivals and fairs, and long days at NYC's playgrounds, it's also a great season for new museum exhibits. Alfresco sculpture installations at the Brooklyn Botanic Garden and the New York Botanical Garden, hands-on math and science fun at the New York Hall of Science, children's artwork at the Guggenheim, the Cloister's 75th anniversary and old-school music videos at the Museum of the Moving Image are just some of what's on tap this spring. Here are the top seven museum exhibits for families making their debuts this spring in New York City.

On the very last day of spring break, a bunch of Mommy Poppins bloggers and our families got together for a private cruise on the East River Ferry. Yup, those are our kids in the photo freezing their behinds off on deck! (The things we make our children do in order to get a good shot.) Even though it felt more like winter than spring, we had an awesome time. We hope your spring break was also full of fun adventures.

Speaking of the season, even though Mother Nature hasn't quite gotten on board, spring festival season still kicks off this month. All of our tri-state-area sites have roundups of the best April fairs and carnivals, including NYC, Long Island and New Jersey. Plus, all of those sites also published their monthly Go Lists this week, highlighting the best things to do with kids in each area throughout April.

If you're already looking ahead to summer, be sure to check out our Camp Guide. We keep adding new posts, like this roundup of five sleepaway camps for kids with food allergies. If it's a vacation you're after, our Travel site just profiled the gorgeous Sanibel Island, a Gulf Coast barrier isle located off Florida. Or closer to home, you could plan a trip to the Jersey Shore. Although it took a beating from Hurricane Sandy, our New Jersey site has an update on recovery efforts at a number of Jersey Shore hot spots so you know the deal before you go, as well as ways you can help areas that are still rebuilding. And of course nearby Liberty State Park makes for a fabulous spring day trip... and if you grab the ferry there you can appreciate NYC from the water, just like we did earlier this week.

Here's what else we covered on our NYC site this week, including big news about Mommy Poppins expanding to Westchester and more.
