My one month baby sleep whole day n stay awake mostly at night please help what should I do

A. it is normal as babies do not have normal sleep pattern and do not have day and night concept. some babies stay awake whole night and sleep in the morning while others are opposite. baby learn to sleep at night between 3 to 12 months of age work on keeping your baby days bright (i.e. don’t nap your baby in a pitch-black room) and active – play with your baby for a bit between feedings. Then, focus on keeping nights dark and boring – feed your baby and put him right back to sleep in a dark room. This will help to gently shift your baby’s sleep rhythms.
