HALO SleepSack swaddles are available in the following sizes:
• Preemie: 14 - 19 inches / birth - 5lbs
• Newborn: 19 - 23 inches / 6 - 12lbs
• Small: 23 - 26 inches / 13 - 18lbs
Sizing: HALO size recommendations are based on average growth (50th percentile). Babies who are larger or smaller than average may need a different size. If your baby's weight or height exceeds the recommended range, move to the next size.
Fit: The SleepSack should fit snugly around the torso and allow room for legs to bend naturally into a frog-leg position. The wings should be able to be wrapped securely around your baby's torso.
Toe Room: It's okay if your baby's toes touch the bottom of the SleepSack, provided they can still comfortably bend their legs.
