My baby's usually is awake during the night and sleeps for only 4 hrs during the day. He will complete 12 months soon, is it normal?

no dear, this is definitely not good for his health, as at this age babies need at least 12 to 14 hours of sleep. please try to help your baby sleep more during the night, by bringing the sleep time ahead. if required, you also go to bed early with him. and if he wakes up at night, avoid indulging him in play. he will soon learn to fall back to sleep. in the day, encourage nap time by reducing the amount of light and sounds in the room. give him a warm bath and a nice massage, so that he calms down.
