A three-week-old boy born full-term, normal spontaneous vaginal delivery without complication is brought in by his father because he received a letter in the mail that he did not understand about some laboratory tests for his son. The father is not sure about the baby’s eating habits, but states that “he’s a crier”, and sometimes vomits before feedings. He is afebrile and his vital signs are normal. The physical exam is significant for a sleepy newborn with a hyperpigmented scrotum. His weight is 3.7 kg, the same as his birth weight. What is the most appropriate management?
A. Do a head-to-toe exam looking for causes of “increased crying”, and, if negative and tolerates fluids by mouth, refer to his pediatrician.
B. Check the baby’s blood glucose, and if normal and eating in the ED, refer to his pediatrician.
C. After a thorough history and physical, if negative, refer to Failure to Thrive clinic
D. Draw blood for serum chemistry
