I just found out that my baby girl (almost 3 months old) might have a larger heart than she should for her size. She is breathing faster than is normal for her size. She is puking 1-2 times a day. She has a horrible cough. She is also coughing up mucus, and once it sounded like she was having trouble breathing.

She has an appointment with a cardiologist on Friday, and I am extremely scared of what they might find!
