Today, he has become more sluggish and has exhibited poor feeding. He has produced only 2 wet diapers in the past 12 hours. Throughout this time, he has also refused to move his right lower extremity. He was born at 39-weeks gestational age without complications and was discharged 1 day later. His mother received all routine prenatal care and has no medical problems. The patient’s 18-year-old father is not involved with the family. The patient and his mother live with his grandparents.
