Logan is a four-day-old newborn infant. His birth weight was 7 lb 2 oz. Mom and Logan were discharged from the hospital two days ago and Mom has been breastfeeding Logan exclusively. He sleeps a lot and when he is awake, he seems to cry all the time. Like many first-time moms, Logan’s mom is worried that he is not eating enough. At his first well-baby check-up, Logan’s weight is 6 lb 14 oz. Is Logan getting enough to eat?
