My 55 days old baby sleeeps approximately 10 hours total. Is it sufficient. Does it have any negative impact on my baby.

A. While every baby's sleep needs are slightly different, a typical 2-month-old sleeps a total of 14 to 17 hours a day, including four to six naps. Day-night confusion should be subsiding, and you may see baby settle into a rough pattern of 60 to 90 minutes of awake time followed by 30 minutes to two hours of napping.
