💙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.
