Disney's most famous characters Mickey and Minnie join the original HALO ® SleepSack ® Wearable Blanket collection to make safe sleep more magical than ever. SleepSack ® nestles baby like a soft blanket, without the risk of sleep-related dangers. Design details include a zipper that opens from the bottom for easier changes, and a roomy, extra long sack. That means it's hip healthy and you won't have to size up as quickly. 100% cotton is soft, breathable and extra gentle on delicate baby skin.  Safety Reminder: Always place your baby on their back for sleep. And, never place anything in the crib with your baby. No pillows, bumpers, toys or loose blankets. The American Academy of Pediatrics recommends the use of wearable blankets to keep your baby warm.
