2. Setup and Usage
How to Dress Your Baby:
- Lay the swaddle sack flat on a safe surface.
- Unzip the dual zipper completely.
- Gently place your baby inside the swaddle sack, ensuring their arms are positioned within the arm curves.

Using the Foot Button:
For increased ventilation or to allow your baby's feet to be free, unbutton the foot openings at the bottom of the leg-split design. This feature is also beneficial for taller babies or to prevent overheating.

5. Important Safety Information
- Always place your baby on their back to sleep.
- Ensure the swaddle is snug but not too tight, allowing for proper breathing and hip movement.
- Discontinue swaddling when your baby shows signs of rolling over, as recommended by the American Academy of Pediatrics (AAP). The leg-split design of this swaddle allows for safer rolling once your baby reaches this milestone.
- Monitor your baby for signs of overheating, such as sweating, damp hair, flushed cheeks, or heat rash. Use the foot button feature to increase ventilation if needed.
- Ensure no loose fabric can cover your baby's face. The ribbed waistband helps keep the chest fabric in place.

8. Troubleshooting
