Love To Dream Baby Sleep Sack, Swaddle Up Self-Soothing Swaddle Sleep never felt this snug with our Swaddle Up Self-Soothing Sleep Sack, available in a range of classic colourways & prints. Our “Arms-Up” baby sleep sack, also known as a swaddle or wearable blanket, is designed to allow baby's arms to be positioned upward and close to their face while they sleep. Eighty-three percent of parents reported an increase in hours slept by their baby when using Swaddle Up. Baby's Natural Self-Soothing Sleep Position Most babies are more comfortable with their arms near their face, as this mimics the fetal position they were accustomed to in the womb. Allowing their arms to be up can enhance their sense of security and comfort during sleep. The ability for babies to self-soothe by touching their face or sucking on their fingers can be comforting. An Arms-Up sleep sack facilitates this natural soothing mechanism, promoting better sleep for baby. Babies have a startle (Moro) reflex that can sometimes wake them; swaddling with Arms-Up can help reduce this reflex and minimize unnecessary disturbances. Easy to Use, Hip-Friendly Design Our baby sleep sacks are designed to provide ample room for baby's legs and hips to move naturally, allowing for healthy hip development. The clever two-way zipper mechanism means quick and easy diaper changes for any parent, grandparent, or carer, even in the middle of the night. This 3.5 TOG material is ideal for room temperatures below 61 °F. Fabric content: Outer & Lining: 93 % Cotton, 7 % Elastane; Filling: 100 % Cotton.
