If it pours on Saturday or Sunday, some of our outdoor event picks may be canceled, rescheduled or move inside. We're doing our best to keep this post updated, but if it does rain on the weekend, be sure to check the events' official websites before heading out to find out if anything has changed. Mothers Day is Sunday, so moms, this weekend should be all about you. Why don't you decide what to do on Saturday and Sunday? (As if you don't do that most of the time anyway.) There are lots of fabulous outdoor activities including a slew of cool school festivals, Socrates Sculpture Park's annual Kite Flight, a no-cost Brady Rymer concert in Battery Park and the New York Botanical Garden's Mothers Day Garden Party. Plus, after being closed for many months due to damage caused by Hurricane Sandy, Tribeca's popular Pier 25 playground is set to reopen on Saturday.

If Mother Nature decides to make it rain on our big weekend (how could she?) there's plenty of indoor fun too beyond Mother's Day brunch. My family plans to check out the Parade of Trains celebration in Grand Central Terminal. And on Saturday you can get geeky at the Kids Comic Con in the Bronx or bring your natural treasures to the American Museum of Natural History for Identification Day.

These are just a few of the great things going on this Mother's Day weekend. All of our best bets are below, You can find additional options in our Event Calendar and our Spring Fun Guide. Happy Mother’s Day to all of you from your fellow moms at Mommy Poppins.

Are you ready for some free fun? Because there's plenty of it this weekend. Spring festival season kicks into high gear with the return of the New Museum's biennial IDEAS CITY StreetFest, Hippo Playground's annual spring fair, a slew of school fairs and the NYC Irish Dance Festival, which kicks off this season of Summer on the Hudson.

Lots of our top event picks for the month of May take place this weekend as well, like the Super Sonic Kindie Music Festival, citywide volunteering initiative It's My Park Day and the New York Road Runners' no-cost Youth Jamboree. Plus there are free concerts by Gustafer Yellowgold and Sugar Free Allstars, the annual Cinco de Mayo Mexican Parade and free comic books will be given away in all five boroughs.

Are you good at making tough decisions? We hope so, because there's a slew of amazing activities to choose from this weekend, including three picks from our April NYC Go List: the Brooklyn Botanic Garden's Sakura Matsuri: Cherry Blossom Festival, the Parks Department's no-cost celebration of Street Games in East Harlem and the Tribeca Film Festival's free Family Street Fair.

While those three annual family favorites promise to be super-cool, they'll also be super-crowded. So you might want to try hitting an event that's a bit more under the radar like Park Slope's Fifth Avenue Family Fest, the Queens Botanical Garden's Arbor Festival or your local YMCA for Healthy Kids Day.
