My little man has been coughing for about a month now, thought it was just a simple cold cough because that’s all it ever sounded like. I would put Vick’s on his chest and it would go away for about 8 hours but then be back. He had his 18 month appt. and  We told his pediatrician and she said If it last more than 3 weeks to let her know. At that point he already was coughing for 2 weeks. Yesterday he was coughing so bad (this was the first time the cough sounded like this) he was throwing up. So we went to urgent care.. he got tested for whooping cough and we are waiting for the results. I am so scared. He was fully vaccinated,  was not around anyone that I knew with a cough, so how could this have happened ? Any advice. I feel terrible.
