Today went to see her doctor, never do echo, only physical examination, doctor say she look very well, baby is indeed doing really well, can walk, can run, can climb, can talk and etc, developing normally like any other kids. Then out of the blue doctor mentioned a small leakage, came as a surprise, we thought the operation went very well, so how come still have leakage, but today never do echo so don't really know much, I think she found it in last echo results, so she scheduled to see baby in September. I think no need to worry so much, I did some search online and some people say it is quite common to have tiny leakage after surgery, some will close by itself but who knows, last time we also thought her ASD may close by itself, in the end never close. What's most important is that she is doing well now.
