Not really sure what it involves. DS3 has a murmur picked up when he was a few days old, they initially said it would "almost certainly" disappear but it didn't, so he is apparently being referred to a different hospital (Harefield apparently) for an echo.
Apart from that we've been given zero info. I've looked up some stuff about murmurs, but there's so much info its not really helpful until we know if its due to a defect or not. Any idea how long you normally have to wait for the referral? How long does it take and will it be distressing for a small baby? Thanks.
