Crrrrrrrack!

Sparrow, a new baby store, has hatched.

Tucked inside its North Hollywood nest, you’ll find lots of green design for the little ones. Let the chickadees play with Tree Blocks while you cruise through Royal Handicraft’s felt backpacks, Kate Quinn Organics collared onesies, Happy Green Bee’s stripey knits, and Sprout’s brightly colored bamboo and organic cotton tees.

Most of the handpicked designers are living, breathing moms right here in Southern California.

Making this place a real good egg.

Sparrow, 3266 Cahuenga Boulevard West, at Barham Boulevard, North Hollywood (323-512-7122 or shopsparrowla.com).
