I took Joel to his 18-month appt. the other day and the doctor discovered that he has a heart murmur. He wants Joel to go for an echo/EKG next week. I'm, of course, freaking out. The doc did say that many kids have a murmur at some point and they grow out of it, but he wants to make sure it's nothing serious. I'm trying to be positive, but I can't stop thinking worst case scenario. Has anyone experienced this? What was the outcome? Thanks.
