The Living Textiles Smart Sleep 2-in-1 Zip-Up Swaddle helps babies feel safe and secure as they adjust to life outside the womb. The natural hand over heart position, similar to a baby's position in the womb, helps reduce the startle reflex allowing for a longer, sounder sleep. Our 2-in-1 design allows babies to gently transition from swaddling to arms out, one arm at the time; making this swaddle the smart choice for every baby.
