in their bedroom, and 30 % of parents have reported that watching a television program enabled their children to fall asleep.3 Although parents perceive a televised program to be a calming

sleep, cause anxiety about falling asleep, and shorten
sleep duration.41 Specifically,

Physiologic studies have demonstrated that,
in general, swaddling decreases startling, 301 increases sleep duration, and decreases spontaneous awakenings.310 Swaddling also decreases arousability (ie, increases cortical arousal thresholds) to a nasal pulsatile air - jet stimulus, especially in infants who are easily arousable when not swaddled but less so in infants who have high arousal thresholds when not swaddled.301 One study found decreased arousability in infants at 3 months of age who were not usually swaddled and then were swaddled but found no effect on arousability in routinely swaddled infants.301 In contrast, another group of investigators showed decreased arousal thresholds310 and increases in autonomic (subcortical) responses311 to an auditory stimulus when swaddle
