Babies cry. It’s normal, but can be alarming for new parents, especially because sometimes we just don’t know why. It’s common for parents to be concerned about how much crying is normal. Crying may increase during the first six to eight weeks, especially in the late afternoon and early evening, but two to three hours of crying a day in the first three months is considered normal. More than three hours of crying a day may be a cause for concern, especially if this is different or unusual for your child.
