Update: As of April 2014 the New York State Education Department has decided to cancel its contract with inBloom. It was a hard-won fight!

There's a story I've been following for a while now about the controversy surrounding a company called inBloom. Backed by the likes of the Bill and Melinda Gates Foundation, inBloom stores student data in an online cloud, including grades, test scores, teacher observations about behavior, and even more sensitive information like special education status, family history and disciplinary records. The supposed goal is to help teachers and schools easily track each student's progress, provide more personalized instruction and inspire digital developers to create new and innovative educational tools. However, many parents and education activists across the country are concerned that inBloom violates students' privacy in a big way and that the data may end up being compromised or sold to the highest bidder.

While inBloom is a national venture, as of now only three states plan to use its services, including New York State. It's important to note that out of the original nine states who were interested in inBloom, six have pulled out due to privacy concerns. According to an article in last week's New York Times, the New York State Education Department has already uploaded data for 90% of its charter and public school students, and there is no way for individual districts, schools or families to opt out. But there are things parents can do to voice their concerns and possibly stave off or at least change the scope of inBloom.

Unfortunately, National Costume Swap isn't happening in 2015. My eight-year-old daughter is the Imelda Marcos of costumes. Every Halloween she's invited to a terrifying number of celebrations and she insists on a different outfit for each one. I happen to love dressing up, too, so, I admit, I indulge her. Trouble is, she outgrows her costumes much more quickly than I do mine—we never get more than one Halloween season out of them.

Instead of throwing all of those barely used costumes into the donation bin (or worse, the landfill), we've found a better, eco-friendly option that saves us money and is actually pretty fun: Halloween costume swaps. At these community events, you trade your child's old costumes for new-to-you outfits. My daughter enjoys tearing through tables piled high with outlandish getups, and I love hanging on to my cash.

Costume swaps have really taken off in popularity in recent years as families become ever more frugal and environmentally aware. In fact, there's even an annual National Costume Swap Day! This year's edition officially takes place on Saturday, October 12, but local community organizations across the country hold costume swaps on various dates throughout the month. We've got the scoop on how to find costume swaps in your area and tips on how to host your own.

I feel like summer just ended and school just started. Yet already it's fall and my daughter is complaining because we haven't figured out our family Halloween costumes. To help you avoid seasonal nagging in your home, we've started overhauling our NYC Kids Halloween Guide, including updating our roundups of pumpkin patches near NYC, on Long Island and in New Jersey, as well as posts about popular Halloween happenings that require advance tickets like the Great Jack o' Lantern Blaze in Historic Hudson Valley and the New York Botanical Garden's Haunted Pumpkin Garden.

Other posts of note: Our Westchester site wrote about the new Mount Kisco drop-in creative spot, Arts Garage, part of the popular go-kart track and bowling alley Grand Prix. Our bloggers in Los Angeles shared ideas for managing your child's food allergies in school and at parties. Meanwhile our Boston site has tips about being a good spectator at your kids' sporting events and 20 ways to ease the pain of flying internationally with a toddler. That info should come in handy if you're inspired to visit Bristol, UK after reading our post about all the fun things to do with kids there.
