Anger - The cry tends to more turbulent. It usually develops between three and 12 weeks of age and comes on during the end of the day. Though crying is communication, babies don't always communicate perfectly. Think about what has been going on in your baby's life recently. Consider the time of day.
Many babies have a time during which they are very difficult to console.
According to the American Academy of Pediatrics' Caring for Your Baby and Young Child, the fussing and crying seem to be baby's way of getting rid of excess energy. Afterwards he or she may even be more alert, or sleep better. Of course, excessive crying can be a warning sign of a serious problem. If you feel your baby is crying too much, contact your pediatrician. In the meantime, stay calm.
