The Happiest Baby Sleepea Swaddle is a revolutionary baby sleep solution, endorsed by the New York Times as America’s best swaddle. Designed by Dr. Harvey Karp, this swaddle has been recognized for its role in promoting healthy hip development and ensuring safe, comfortable sleep for your baby. Its breathable mesh design allows for optimal air circulation, reducing risks of overheating, while the snug inner flaps offer a gentle, womb-like embrace that soothes and calms. The tie-dye rainbow pattern adds a fun, stylish touch, making it a favorite among parents and babies alike.
  Use the Happiest Baby Sleepea Swaddle to help your baby sleep better and longer. With its unique 5-second swaddle design, it helps babies self-soothe and resist startles, leading to improved sleep quality. The medium size is ideal for newborns up to 6 months, while the easy-open zipper allows for simple and quick nighttime diaper changes. Perfect for transitioning to arms-free sleep, this swaddle supports independent sleep training and offers peace of mind for parents. However, it is not recommended for use with the SNOO Smart Sleeper—only the SNOO Sack should be used in that product.
