Two of my children have heart murmers its very common most children out grow them by the age of 5 I believe. Im about to have to take my children to a cardiologist because they want to check and make sure everything is ok. There 2 and 1 years if they havent seggested your son be seen by a specialist then they probably think he will out grow his. Ill pray for all of our babies.
They day my son was born he had one his pedi said it happens to many baby after birth the valve doesn't close but she told me normally within 24hrs it goes away. The next day pedi checked him again n it was gone. I dnt no much about them n wasn't aware until that day. i hope your babys goes away. sry i couldnt give more info to u
Heart murmurs during infancy are very common, most babies will outgrow them. It has something to do with the valves not closing quite evenly and most of the time is completely harmless. I never outgrew my heart murmur but it doesn't cause me any problems as an adult.
Idk what causes them but how far along are you. I read somewhere as the heart develops heart murmers can arise and the baby can be completely.fine. also my dad has a minor heart murmer and the chances of something going wrong.are almost as.bad as winning the lottery some heart conditions aren't very serious sorry I.can't help more :(
