My baby was diagnosed with heart murmur after he was born. He has a small (or medium) hole in his heart and being checked every couple months. Its congenital heart condition called Ventricular Septal Deffect (VSD). He is thriving and a big eater. The doctor says not to worry, it may close itself. But now he is almost 1 year old and last time we went to doctor, he said it still sounds the same as before but since my boy is growing well, he said he will check him in 6 months. Is it really that common thing? I'm starting to feel a bit worried about whether it will ever close spontenously, or we have to take other measures. Please share your experiences if u have any.
