The Clean & Safe Angle

Crafted from soft cotton knit, the SwaddleDesigns Baby Sleep Sack prioritizes your baby’s comfort and safety. Cotton is a breathable, non-toxic material, making it a great choice for infants who have sensitive skin. You can rest assured that your baby is snuggled in a product that is free from harmful chemicals commonly found in synthetic fabrics.

Is It Right for Your Family?

This sleep sack shines for families looking for a safe sleep environment for their newborns and toddlers. It’s particularly beneficial for parents who want to transition away from traditional swaddling methods as their baby grows. However, if your child is already accustomed to sleeping with blankets or prefers a different sleep style, they may not take to it as readily.

What Makes a Baby Sleep Product Safe

For anything your baby sleeps on or in, safety and air quality come first. We prioritize firm, flat surfaces (no inclines), breathable materials, and certifications like GREENGUARD Gold (low chemical emissions) and OEKO-TEX or GOTS for fabrics. We avoid added flame retardants and vinyl. A safe sleep space is alone, on the back, on a firm surface, with no loose bedding before 12 months.
