Crying is normal. It is one of the only ways babies have to tell you that something needs to be different. As your baby gets older, she will get better at letting you know what she needs—and she will cry less.
Beginning at about 2 weeks, many babies start to cry more than they did when they were first born. This time is also sometimes called the "period of purple crying." Some babies cry a lot and others far less. This is the time to learn how to calm your baby and how to keep yourself calm if your baby won't stop crying. While it can be frustrating for parents, know that this time is temporary, and will probably end by the time baby is 3 or 4 months old. Be sure to watch for early hunger cues, because baby may be too upset to eat if he's been crying for a long time.
