Every baby cries. Crying for one to four hours a day can be normal.
A typical 6-week-old infant spends about three hours a day crying. At first this may be hard for you if your baby has been sick; you may be worried that he / she is getting sick again. Or maybe you feel that you should be able to comfort your baby, and yet nothing you do stops the crying. Do not blame yourself.
Crying is one of the ways that newborns speak for themselves. They often have a distinct cry for separate feelings: hunger, pain or need for attention. There is also the half-awake whimper that indicates the baby is dreaming and will likely fall back asleep.
