Sleep matters! That's why we take pride in every detail of our mom-created, doctor-approved, and backed by science sleep solutions. Our Weighted Sleep Sacks and Blankets feature our proprietary CoverCalm™ Technology, ensuring even weight distribution from your baby's shoulders to toes. This evenly distributed weight is what sets us apart and harnesses the power of deep touch stimulation: increasing serotonin & melatonin while decreasing cortisol. So what does that mean for you? A happy, relaxed, sleeping baby!
