For baby's safety, it is recommended to replace all loose blankets with a wearable one. Aden and Anais' breathable classic sleeping bag is perfect for your baby. Impossible for little legs to kick off, the wearable blanket slips over your baby’s pj’s and zips open from the bottom, making stealth nighttime changes a cinch. Plus, our 100% cotton muslin is pre-washed so it’s super soft from the start and stays that way wash after wash.
