Get medical attention if you notice any of the following:
Your baby is not interested in feeding or is too sleepy to feed at least eight times per day.
Your baby is not wetting their diaper at least two times per day in the first week, or five times per day after the first week.
Your baby doesn't have at least one greenish brown stool during the first three days, or at least two dirty diapers after four days of age.
Your baby cries all the time and can't be comforted.
The white parts of your baby's eyes start to look a little yellow.
If your baby has a fever of 38°C (100°F) or more, call your doctor or midwife right away or go to the emergency department.
