Fact: Today's kids are the most sedentary generation in America's history. Only one in three children is active on a daily basis, and only four percent of elementary schools offer daily P.E. "That's not just bad for their bodies, it's also bad for their minds because being less active can actually hurt kids' academic performance," First Lady Michelle Obama said at an event we attended today announcing the new Let's Move! Active Schools initiative. The program aims to help schools create active environments where students can get 60 minutes of physical activity before, during, and after the school day, and the goal is to reach 50,000 schools during the next five years.

"This is about so much more than keeping our kids physically active," Obama said. "And it's about more than making sure that they do well in school. I mean, this is about giving our kids the structure and support they need to thrive in every single aspect of their lives. It's about giving them something to strive for, something to hope for, somewhere to belong. And physical activity is a critical part of that broader effort."

While Obama stressed that we don't need "new sports leagues or fancy equipment" to get kids moving (she suggested after-school running clubs or dance flash mobs between classes and cited her own love of double Dutch), the far-reaching program does come with some major expenses, and to help out, Nike has pledged to invest $50 million in the effort over the next five years.

Every parent deserves the occasional night out on the town, but sometimes the preparation involved turns the evening into more work than it's worth. Securing a sitter, factoring in the additional cost, prepping the sitter . . . once you're a mama, there's definitely more to a night out than picking out a great outfit and calling a cab. Allow us to make at least one of those steps a bit easier. Since you're likely to be rushing out the door when your sitter arrives, we've compiled an all-encompassing checklist of what she needs to know before you head out of the house.

1. The All-Important Contact Info: Your sitter probably already has your number programmed into her phone. Make sure that this is in fact the case, that her battery's charged (or she has access to a charger), and that once you're out, you're accessible as well. If you're at dinner or a movie, keep your phone in your pocket and on vibrate. Give her a backup number of someone you'll be with, too — just in case.
2. Food and Drink 411: It's better to over-inform than leave out pertinent information when it comes to your little one's nutritional needs. Don't assume anything, and be very thorough in reviewing what your child/children can eat and drink, being sure to highlight any allergies.
3. Where Am I?: Make sure that your address and (if applicable) landline are written down. In the unlikely event of an emergency, it's crucial that your sitter be able to tell the police or fire department where she's located. Also relevant in the more likely case of a pizza delivery.
4. House Tour: If it's your sitter's first time to the house or apartment, have her come a good 30 minutes early so that you can show her around and answer any questions without being in a rush.
5. Baby Bio: Again, if you're using a new sitter, you'll want to spend a few minutes going over your child's age, likes/dislikes, and what he or she can do and can't do. What's obvious to you may not be obvious to her, so be thorough!
6. Just In Case: In case of an emergency, you should be the sitter's first call. But having the numbers of the nearest hospital, your pediatrician, poison control, fire department, and police department handy is a smart move.

If you've got little style setters at home, you'll want to mark your calendar for this June, when New Zealand designer Karen Walker's debut childrenswear line will launch at Uniqlo locations in the US and around the world. With "child geniuses" as the inspiration for the collection, it's set to encompass 18 pieces of mix-and-match apparel for girls between the ages of 3-11. The dresses, tops, pants, and skirts will feature the designer's signature alphabet print and a new pattern that's reflective of a child's doodles on graph paper.

"We drew inspiration from the look of Karen Walker collections and with a little help from my 5-year-old, Valentina, we picked out some of our beloved signature styles such as frill hem sweatshirt dresses and boat pants and restyled them for kids," Karen Walker said of her line. "As a brand with working parents in the team, we wanted to create a fun and spirited kids' collection that used high quality utility fabrics and would be kid-friendly and a great price."

Pieces will start at $16, and the collection will be in stores on June 3. In the meantime, get your fix for the affordable, adorable Uniqlo Kids line here!
