Sweetie, don t lose hope. A heart murmur is quite common in children. My son was diagnosed with it and has outgrown it. He was 3 when diagnosed and is now a 15 yr. old healthy young man. It is great that the doctor found your babie s murmur this soon and has referred him to a hospital for testing. Don t beat yourself up. There is nothing you have done wrong and nothing you can do about it but following your doctor s advice. Just don t despair, as your mood will be picked up by your baby. The shortness of breath may very well be related to the murmur, but only testing will give you the peace of mind you need right now. Make sure that you keep the baby close by, if nothing else, place a monitor in the babie s room and one in your bedroom. Don t drive yourself crazy, sweetie, get an appointment as soon as possible and make sure you mention the breathing problems. That ought to get you seen right away. I don t want to scare you, but if the babie s color changes or he/she starts coughing, proceed to the nearest ER, or better yet, call 911. I hope you have somebody with you, if not, don t hesitate to come back and contact me via Yahoo. I ll try and help as much as possible and/or will try to talk you through the morning. Hang in there. Your baby needs you. MsB.
