First Few Days After Birth
Urine and Bowel Movements
In the first 2 days of life, urine produced by a newborn is concentrated and often contains chemicals called urates, which can turn the diaper orange or pink. If a newborn does not urinate within the first 24 hours of life, a medical evaluation may be needed. The first bowel movement is a sticky greenish black substance called meconium. Every baby should pass meconium within the first 24 hours after birth. If a baby does not do so, the doctor may do tests to determine whether there is a problem. Occasionally, for instance, a birth defect may cause a blockage of the intestines.
