2 months old baby had cough and cold and was treated with antibiotics via iv. Baby still has cold for 10 days now with no fever but stuffy noise

Re check! If your infant is still congested-have your pediatrician evaluate to determine if congestion is from stuffy nose or from the lungs-wheezing-"bronchiolitis" cough. This evaluation will determine what to try for "comfort" care. Often times, the congestion takes 1-2 weeks after your event with IV antibiotics to subside.
