Hello, I understand your concern It is a common concern, but not all newborns sleep exactly 20–22 hours. Most healthy newborns sleep 14–18 hours/day, usually in short stretches of 2–3 hours at a time. Some babies are more alert or sensitive to light, noise, or feeding cycles, and that can temporarily affect sleep. If your baby is: Feeding well, Passing urine ≥6 times/day and regular stools, Gaining weight steadily, Active and not unusually fussy, then sleep variations alone are not worrisome at this age.

Some babies are more alert by nature, especially early on. If the baby is feeding and growing well, this is usually not a cause for worry

Not all the baby sleep exactly 20-22 hrs It depends upon surrounding environment of the baby how you take care them. Even if baby sleep 15-18hrs also enough

Circadian rhythm takes time to develop as the baby comes out of the closed confines of a mother’s womb - no light, only the humming comfort of the fluid around and rhythms outside. We expect normal full term newborn to sleep approximately 16-18 hours per day, pattern of sleep and wakefulness is irregular, the longest continuous sleep period being 2.5-4 hours, often synchronised with feeding times So expect the baby to get up for feeds - it’s good for him-, after a wet diaper ( they hate being wet), and for any other reason which causes him discomfort - could be heat, noise, light. And he will cry! That’s the only way for him to express himself. It’s also a comforting sign for paediatricians - crying baby is a healthy baby

See for good feeding and do burping after feeding ....sleep upto 15 hours is normal.....see urine feeding and activity normal then all is good

If baby is accepting feed well and passing urine 6-8 times per/day . Sleep pattern is not concern . Some babies will sleep for 16-18 hrs . No need to Worry about it . Sleeppattern will b genetic also .
