Long story short, my niece was diagnosed with pneumonia three or four days ago. All of a sudden, my DD who has had a cold for two has developed a wicked cough going into last night and into this morning is coughing quite a bit. We had her humidifier going and vicks on her chest before bed. The kicker is we are having DD's birthday party today! Do you if know is pneumonia catchy? Also, I am wondering if I should cancel party so I don't get other people sick... My pedi's office doesn't open until 8:30 so I will call them to ask for advice but just curious if any of you had experience with this. Thanks!!
