One of my favorite things to do over holiday break is look back through the 500 or so posts we've published throughout the year to remind myself of all the cool new places for kids that have opened since January. (Yeah, I'm nerdy like that.) Every year, NYC welcomes new state-of-the-art parks and playgrounds, outdoor ice-skating rinks, interactive indoor play spaces and even a museum or two, and 2013 was no exception. Even if you're still working your way through our best new family destinations post from 2012 (or 2011 or 2010), here are 20 brand-new New York City attractions that opened in 2013 to add to your must-explore list.

Jump, climb, run, skate - some kids just have to keep on moving. Lucky for these kids, there are plenty of indoor spaces to host a birthday party in Boston that allow kids to harness some of that energy. Since the party places are all indoors, no need to worry about rain, snow, heat or cold. And what may be the best thing about hosting at an indoor birthday party place? No mess, minimal fuss, and great fun for parents, too!

Finding a babysitter on New Year’s Eve is harder than getting your one year old to eat spaghetti without getting it in her hair.  And harder than getting your eight year old to clean her room.  (Well, maybe it’s not quite that hard…)
