You have a pediatrician who has a 24 hour question/answer and advice line. Call the regular office line and, if it's after regular hours, you will get to an answering service. They relay that info to your doctor, no matter the hour or the day. There is always a pediatrician on call. You call the number and you do NOT spend time on the internet for medical questions and answers from total strangers who are moms, not doctors, especially for an infant. You want medical advice from the doctor who knows your child and the local resources (urgent care, Emergency Room, etc.). Get off the computer and call the doctor.
