7 startups that have grown with their millennial fan base by introducing baby and kids' collections

Allbirds, the internet's favorite sneaker startup and maker of the comfiest pairs on earth, aptly named its kids' collection "Smallbirds" (we know — it gets us every time!). Toddlers and kids can run around comfortably in the company's original Wool Runners made from sustainable (and super soft) merino wool. Though the shoes have laces, there's also an elastic band underneath the tongue on kids' pairs so they slip on easily but won't slip off. Plus, parents can clean them up easily in the washing machine.

Recognizing that socks are one of the most requested but least received items in homeless shelters, Bombas was founded with a mission to provide socks to those who need them while selling socks to those who want them. The company has now donated over a million pairs [fact check... think it's 10m]. Their kids' socks are designed with grippy bottoms so they can run freely around the house without slipping, sliding, or crashing into walls (as kids are wont to do).

Launched exclusively online in 2014, Mahabis makes slippers for adults and kids that can easily be worn outside the house for errands, dog walks, grocery trips, and checking the mail. The original design for adults had removable rubber soles for indoor-to-outdoor use, but the newest iteration has them fully attached. The stretchy heel tab makes them easy to walk in, but they can also be folded down for a full slip-on experience.

Away's trendy suitcases feature ejectable batteries that are TSA-approved so your devices stay powered throughout your trip. The kids' versions are no different — they're just a little smaller and much more manageable for little ones to carry. They come in nine different colors, and Away also has a selection of fun and substantial stickers that kids can use to customize their suitcases.

West Coast startup Rothy's makes flexible, comfortable women's flats and loafers out of spun recycled plastic. This year, they launched a girls' line consisting of the ever-popular loafer style, which won't slip off their little feet as they run, jump, and play. As with the adult pairs, they're machine washable, comfy, and come in tons of fun colors and patters.

Bedding startup Parachute, which launched in 2014, only took three years to put out its first collection of baby bedding. It now makes crib sheets in the company's beloved percale and linen materials, along with a selection of luxurious cashmere blankets, quilts, a pillow, and the sweetest little hooded baby towels you ever did see — all in gender neutral greys, whites, and pastel blush colors.
