Well, that, and mud.
Lots of ooey, gooey have-a-boot-stompin-good-time mud.
As I'm sure you moms and dads out there already know, the stuff's like a kid magnet.
So instead of having your younglings spend rainy days with their little noses smashed up against the windows just itching to get outside and puddle jump, outfit them in a Splish Splash Rain Jacket and Pant Set (shown at top left, $47) from Kushies.
The jacket keeps rain out of little collars and sleeves with a snuggly lining and hooded visor, and its two front pockets with an extra in the back are perfect for holding tot-sized treasures like sun-bleached stones, Pooh sticks and a wiggly worm or two.
There's no need to worry about little legs getting drenched either, since the matching rain pants are fully adjustable at the waist and hems, ensuring that your kiddie will be as waterproof as a pond frog .... which wee ones might also be tempted to stash in the pants roomy cargo pocket.
And, for those sweet peanuts who are just too young to brave harsh elements, Kushies offers a whole range of offbeat developmental toys, both soft and sturdy for hours of uninterrupted indoor play. 
Inspire baby's budding imagination with more than black and white with Kushies Zolo Mobilo (shown at bottom right, $60), whose crazy carnival-themed characters are sure to stimulate bitty minds and sensory receptors.
Five cuddly, zany Kushies creatures attach (and detach) to a colorful, mirrored canopy and a coordinating wooden arm for secure crib placement. And though all that color might not lull baby into a quiet dreamworld, you can bet awake time will filled with fancy-free Alice in Wonderland-like fun.
Babies and tots who like a blankie to snuggle will delight in Kushies extra cuddly and colorful Max Monkey Blankie (shown at bottom left, $24), a friendly-faced character with tons of hug appeal. 
Its plush fabrics and understuffed body make it lightweight and easy for little hands to grasp, and the included zippered laundry bag makes clean up from too much love a snap.
Want more monkeyshines? Max Monkey is also available in pillow form and as a plush toy.
And let's not forget mealtimes. Regardless of whether or not your pint-sized nibbler is still noshing a liquid diet or munching more grown-up fare, Kushies Premium Style Waterproof Bib With Sleeves (not shown, $11.20-$14) makes sure to keep food off of clothes and on the floor or tabletop, or walls ... you know, where tots think it belongs.
A soft Velcro closure keeps the bib in place and comfortable, while a catch-all pocket intercepts stray dribbles and crumbs, and with sizes for infants, toddlers pre-schoolers, these handy-dandy bibs can do double duty as art smocks, too.
They're even perfect for making mud pies.
