The multi-layer sleeping bag is ideal for transitional periods thanks to its four layers, providing your baby with a sense of security and comfort when transitioning from a swaddle to a sleeping bag. This baby sleeping bag can be easily slipped over pajamas and replaces loose blankets in the crib for a safe night's sleep. The sleeping bag allows air to circulate and reduces the risk of overheating for your baby, ensuring that both you and your baby can sleep peacefully. The practical zipper opens from the bottom, making nighttime diaper changes simple. Perfectly suited for medium room temperatures (20 to 22 °C). Machine washable: remains soft after every wash. All materials from aden + anais are made without azo dyes. All packaging from aden + anais is recyclable and meets the requirements of the "Green Dot Initiative.".
