Our friend's child had a cold a few weeks ago, which turned into a cough. She was eventually diagnosed with bronchitis and a sinus infection. Fast forward to now and both she and her brother have this weird cough where they cough really hard and it has an off sound at the end. Not a whoop, but just an odd sound. Mom told me daughter puked the other night because she was coughing so hard. DS started coughing two days ago. I thought it was his asthma because this is his "time" where we usually have issues. Tonight, he started coughing so hard that he had that weird sound. Now I'm freaked out. Should I take him in or wait and see? Could this be whooping cough? I've been freaked out by their cough for a few days and whooping cough had crossed my mind. I assumed I was overreacting until tonight I told DH that DS had the weird sound and he says "I hope it's not whooping cough." Which is so abnormal for him to even come up with something like that.
