An 8-week-old previously healthy infant, product of a full-term pregnancy, is brought by his older sister to the emergency department for a fever up to 101.2F. The sister, who is 17 years old, states that she is the primary caretaker for her brother because the only adult at home is her mother who is struggling with cocaine and alcohol abuse. The sister states that although her brother has not been eating well, he is taking in a normal amount of formula and has not had cough, runny nose, altered behavior, vomiting, or diarrhea. Overall, the patient is well appearing. You perform an appropriate workup for this infant with FWS and find a WBC count of 10,000/mm³ , and a UA with 2 WBCs/hpf. You also elect to do an LP and the CSF shows 1 WBC/mm³ and no organisms on Gram stain. 

What is the most appropriate disposition for this patient?
