There are numerous reasons as to why babies cry. Sometimes babies cry because they are hungry, sometimes because of indigestion and stomach pain while some other times, they just cry for no reason at all! Indeed, handling a baby is no easy task. Hats off to all the mothers who have raised and have been raising their kids so well!
In the human kind, crying is the first form of communication. It is the only way a baby communicates to their mother and father. Crying is also a language in itself. Ask most experienced mothers and they will tell you what sort of crying means what for the baby. Over the period of time, mothers tend to understand what the baby is expressing through its cry.
Most of the times, babies cry when they are hungry. Babies also sometimes cry because of fatigue. The first time parents really get apprehensive because they think that the baby is facing certain problems or going through pain that the parents cannot understand. But some babies cry for no reason at all. Your baby will eventually outgrow this habit. Some babies also cry before going to the bed. A bedtime routine and adequate rest during the day is what the baby needs. Babies also cry because they often feel uncomfortable if they have swallowed air. Try and keep the baby upright as this will help them to swallow less air while feeding. Just observe for a few days what suits your baby, what are the certain patterns that your baby follows and what are his sleep timings. You will slowly get to know why your baby is crying and will be able to provide him or her with the right thing.
