weighted sleep sack for baby

They say necessity is the mother of invention—and nothing makes you more inventive than motherhood.

Sometimes that means fashioning a diaper out of paper towels and your older child's underpants (true story). Sometimes that means creating an innovative and life-changing weighted baby sleep sack and totally crushing it on Shark Tank. Tara Williams is the latter.


When her son was about 6 months old, he struggled to sleep for more than an hour and a half at a time. Like so many of us in the first months of parenthood, she was exhausted and desperate for a solution.

"One night we placed him under a heavy throw blanket while sitting on the couch," she says. "I noticed as soon as the weight was on his body, he instantly calmed down. A lightbulb went off in my head: he needs a weighted blanket!"

With the help of her mother-in-law, she created a prototype. The first night her son used it, he slept for 12 hours. After working with pediatricians, NICU nurses and certified sleep consultants on a series of refinements that resulted in a sleep-safe sack and testing rigorously to ensure it exceeded all U.S. Consumer Product Safety Commission Standards, she competed on Shark Tank and secured a $100k investment.

So does it live up to the hype?

Absolutely.

Made from soft 100% cotton that keeps little ones from overheating, Dreamland Baby weighted sacks use the same concepts as weighted blanket—to provide deep-pressure stimulation. It's that cozy reassurance that comforts and calms to help them fall asleep faster and stay asleep longer. They are gently weighted on the front panel only with food-grade, non-toxic inner-bead fill and feature a two-way zipper to make diaper changes as easy as possible. The smallest size comes with a detachable swaddle wing for babies who prefer swaddled sleep.

With hundreds of 5-star reviews, we couldn't be more impressed.

According to one Motherly Shop reviewer, "We used Dreamland swaddle since my baby was born. I bought two sizes for the 0-6 we loved them so much- just purchased the 6-12 now. My daughter falls asleep on her own and wakes up well rested. I have recommended to probably 10 other moms who all use them too!!"
