Who It's Best For
The HALO SleepSack Swaddle is ideal for newborns transitioning from the hospital, parents who want a trusted, pediatrician-recommended safe sleep solution, and families looking for a swaddle that grows with baby through the transition to arms-free sleeping. The 3-way adjustability makes it one of the most versatile swaddles on the market — you won't need to buy a separate sleep sack when baby is ready to move on from swaddling.
How to Use
Place baby in the sack feet-first and zip up from the bottom. Wrap the swaddle wings snugly around baby's arms in your preferred position — arms in for a full swaddle, one arm out as baby starts to transition, or both arms out when baby is ready to move freely. Always place baby on their back on a firm, flat sleep surface.
