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?

What I have heard and read is that a baby should sleep for maximum time, as much as 18 hours. Considering the fact that your baby is not even 12 months, only 4 hours of sleep is too less. I think you should discuss this with a paediatrician. http://www.nhs.uk/Livewell/Childrenssleep/Pages/howmuchsleep.aspx https://sleepfoundation.org/sleep-topics/children-and-sleep
