A newborn typically has around 3 to 4 dirty (soiled) diapers per day during the first week of life. After the initial days when the baby passes meconium (a dark, tarry stool), the stools turn yellowish and you can expect about 3 to 4 dirty diapers daily. Overall, newborns may go through as many as 8 to 12 diapers a day total, including both wet and dirty diapers, but the number of dirty diapers specifically averages around 3 to 4 per day in the early newborn stage.

Details about diaper output for newborns:

• During the first week, expect about 3 to 4 dirty diapers daily.
• Wet diapers are more frequent, usually 6 to 10 per day after the first few days.
• Newborns may go through up to 10 diapers per day combining wet and dirty changes.
• Bowel movement frequency can decrease after a few weeks, but initially, many newborns poop several times daily.
