During the first few months of a baby's life, their only means of communication is crying.
Most infants tend to cry between one to four hours a day.
Older children can show or tell you what they want or what is wrong, but babies can only cry. As a parent, you need to pay close attention to your baby to figure out what he or she is trying to tell you. A sharp scream, followed by a moment of no breathing, and another sharp scream. The baby will usually root, suck on his or her hands and can't be calmed down. A soft, rhythmic cry as the baby tries to pacify and put themselves to sleep.
