hi there, i had the same experience as Sherie. I had a small hole in the heart (vsd) when I was born, which resulted in a heart murmur. The hole closed over by itself witihn a few months. My second son was born with the same thing, which had not closed over 6 weeks after birth but was so small as to not be of too much concern to the specialist. In fact, he didnt recommend any action and said he would see us again when my son was about to start school.
I hope all is ok for you and your baby at the next check.
