my 28 days old baby sleeping long time in day she is not awake during the sleep. we try to awake but is not possible to do it. how to handle this problem?????

A. if the child is sleeping more than normal but xthe growth of the child is proper and in between activity of the child is normal then no intervention is required but if you feel that the child ixs lethargic and is not taking feeds properly then medical examination is very important
