For babies over 6 months, the amount of nighttime sleep stayed fairly constant across agesâabout 11 hours on average, with a range of approximately 9-13 hours (Iglowstein et al 2003). Baby sleep requirements are also met by sleeping during the day.
Babies need between 12 and 16 hours of sleep each day depending on their age. But where they sleep is even more important than how much they sleepâand a new study set to be published in The Journal of Pediatrics found that sitting devices like car seats, swings, and bouncers can lead to injury and even death if babies are allowed to sleep in them.
