Water, water, everywhere, all over our Mommy Poppins sites. We updated two super-popular posts in our Water Fun Guide: the best boat rides for NYC families and our list of the top 20 water playgrounds throughout the five boroughs, including the brand-new Lakeside Splash Pad in Prospect Park. Plus we shared 25 water games you can play anywhere, from your local park to your own backyard.

Looking to get wet outside the the city? Our Long Island site has a roundup of the best beach playgrounds in the Hamptons, while Westchester highlighted six destination parks featuring all kinds of water fun like beaches, pools and water slides. And if your family is really up for a full-fledged water-filled adventure, our Travel site recommends the Grand Solmar Land's End Resort in Cabo San Lucas, Mexico. Warning: Do not click here unless you're prepared to be jealous.

We're smack-dab in the middle of summer break and our SUMMER OF PLAY CHALLENGE. What has your family been doing to make the most of the season? Share your playful pics on social media for a chance to win great prizes. Every week, we're giving away a KaBOOM! Go Out and Play Pack and in late August, we'll be awarding one lucky reader with an Ultimate Summer of Play Bash. So submit your fun photos and then click through all of the entries for new play inspiration.

Here's what else we covered on the NYC site this week:

So many performances are worth seeing this weekend, it’s hard to prioritize! Two are by national troupes—the National Youth Orchestra, an ensemble of kids under the auspices of Carnegie Hall, and The National Comedy Theatre, which is sure to provide a good laugh for young audiences. As an adjunct to this month’s Seeger Fest, join in the Song Circle and Potluck Supper in Honor of Pete and Toshi Seeger to pay tribute to the Hudson Valley’s beloved champions. Returning this week for the second of the four-part series is Puppet Shows in the Amphitheater.

There are also great workshops scheduled for Saturday that are both artsy and practical (and adults would love them too!). One is Create Your Own Blog or Website, and the other is Art & Reuse in the Studio, where participants upcycle used materials.

Keeping kids busy in the summer when school is out can be tricky—but not with the Mommy Poppins event calendar! There you'll find daily listings of options throughout the county, many of which are FREE. If you're willing to venture beyond Westchester, we also have editions in NYC, Connecticut, Long Island, and New Jersey.

What a crazy weather week this has been! Never fear: Mommy Poppins has the inside scoop on the best summer activities to help keep your kids happy whether it's raining, thundering, or just too humid to move. For some indoor fun, older kids will enjoy a visit to the Gilson Cafe and Cinema (ages 12+ are welcome with adults during the week) in Winstead. Just about anytime is the right time for ice cream so check out our guide to the yummiest ice cream shops in Fairfield County (don't miss the Salty Cow!). When you're ready to head back outside, consider blueberry picking or paddleboarding.

For maximum fun, check out 25 Water Activities for Kids, part of our Summer of Play challenge to ditch the schedule and slow down for some good, old-fashioned fun (check out the funlist generator if you need some inspiration).

Have fun out there!

As always, our calendar is full of great events to help you enjoy the weekend.

I know it feels like the summer is just getting started, and I guess in some sense it is. In the "oh my gosh there are so many things I haven't done yet!" sense: totally true.  Have you danced under the stars at the pier?  Have you delighted to Shakespeare by moonlight?  Have you eaten fried everything at the OC Fair or splashed in the water or taken in a concert at the Hollywood Bowl?  Well then, your summer has barely begun.

But in that other sense, the "how many days of summer break remain?' sense, oh boy, we're in trouble. Without actually putting a date on it, I will just say that some of us may be in one-month countdown mode for the dreaded Back to School. So all of you who are thinking "sounds great, I'll get to it later":  there is no later.  It's now or thanks for playing, better luck next summer.

What's a Momma to do? Check out our calendar.  Make note of the super awesome fun times contained therein. (Might I suggest: Piratical, princessical sing-a-long,  storylicious entertainers, out-of-this-world family night, free sweet treat, and gabba-rific meet and greet amusements?) Lay out your blanket, break out the sunscreen and let's get this party started!
