💙Swaddling has been around for ages as it helps to prevent the startle reflex. But forcing the baby’s arms to their sides or over their chest prevents two natural behaviors that frustrate the baby and they fight to get their hands free.

💙First - Over 90% of babies sleep with their ARMS UP around their head when placed on their back to sleep. This is simply a baby’s natural and preferred way to sleep, just like in the womb!

💙Second - All babies are born with the need to SELF-SOOTHE by touching their face and sucking on their hands as they did in the womb. This medically proven behavior is how a baby calms and falls asleep on their own. Traditional swaddling prevents this.

SIZING: Please measure your little one from head to toe and match the length of your baby with the corresponding size next to it on our sizing chart. Please do NOT buy one size up! The bag will not fit until your little one reaches the right age. Small size bags will start to fit once your baby reaches about 3 months old. It is generally recommended to swaddle your infant for the first 2 to 3 months or when they start to roll. Choose a sleeping bag that’s suitable for the season.

SAFE SLEEP: Baby sleeping bags should be sleeveless to aid the heat loss and air circulation. Babies sleeping under traditional blankets rarely sleep with their arms inside. Sleeveless design reduces the risk of overheating. Your baby is covered and warm all night. No more kicked off covers means your baby sleeps more comfortably. Adjustable armholes. Available in three sizes: 3-11, 10-24, and 24-3T months.
