Abby has/had one. It was picked up at 4 days old. We had follow up appointments with her pead and he says he cant hear it anymore. She had another scan at 9 months, but wouldnt sit still enough for it to be of any use. Her pead has asked to have another listen and then send her for another scan when she is old enough to sit still. The information we got at the start was that it would most likely close over, look out for breathing problems and her not being a normal healthy baby.

Shes a perfectly healthy baby and it didnt do her any harm at all.

Good luck
