My 8 month old has her first little cold and I'm not quite sure what I can do. She's having trouble sleeping because of the congestion in her nose and I have tylenol cold drops for infants but the box says to call the doctor at her age. She is 22 lbs. and there is no dosage recommendation for her size either. I really need both her and I to get some sleep tonight, but I feel terrible calling the exchange for something so minor. Is there anything I can do to help her sleep? Will the tylenol drops be safe for her?
