Heart Murmur in 9 months old babies

A

Hi everyone. I'm concerned about my baby. At the last appointment the pediatrician talked about the heart murmur she heard when she visited my baby. She recommended me a cardiologist visit just to make sure that the heart murmur is innocent and there's nothing to worry about. My baby is very active, gaining weight well and developing very well. All the parameters were great. But I'm still very concerned about that. Have you ever experienced something like that in 9 month old baby?

I have the appointment on Wednesday.
