Baby is 3.5 months old (  7 kg ) and vaccine is due in next two days. Baby has cold since 4-5 days . Not runny nose. No fever. Can hear the cold sound sometimes coming from the nose  while breathing. Using Nasomist saline nasal drops at the moment. Baby is otherwise active and shows no other symptoms . In such situation does baby need medications and can we vaccinate her? Thanks in advance.
