What is a startle reflex?

 Swaddling creates a familiar and comforting environment for newborns, reminiscent of the cozy confines of the womb. The snugness of the swaddle provides a sense of security, helping babies feel calm and reassured. Also, newborns have a strong startle reflex that can wake them up abruptly during sleep. Swaddling can effectively limit the jerky movements caused by this reflex, promoting more peaceful sleep and longer rest periods.
