Some of the most common reasons that your baby is sleeping throughout the day are because of an incoming growth spurt or because of some kind of ailment. These are opposing reasons whereas one is a positive thing and the other is something that you should be worried about. In most cases, infants will sleep quite a bit as they are growing at a rapid speed.
