“Get Cosy My Dear” #wait. Sources- PMID 36533224 troy_gass16 on TT Babies spend a large portion of their sleep cycle in active sleep, the infant equivalent of adult REM sleep, which plays a vital role in early brain development. During this light stage of sleep, their developing nervous systems are constantly firing neural signals, causing rapid eye movements, facial expressions, and frequent twitches in their limbs. Because the neurological mechanism that paralyzes muscles during adult sleep is not yet fully mature in newborns, these involuntary signals easily translate into sudden kicks, squirms, and arm flails. Because an infant's nervous system is still developing, these sudden involuntary movements can trigger the Moro reflex, commonly known as the startle reflex. A sharp movement or sudden change in body position can make the baby feel as if they are falling, causing them to abruptly throw their arms outward, pull them back in, and sometimes startle themselves wide awake. Swaddling can be particularly helpful during active sleep, as it gently secures their limbs, preventing these involuntary startle responses from disrupting their rest. #sleep #babies #women
