pingping,
I believe you have misunderstood me, and think that I'm out to put you down or find fault with your experience.
At no time, do I intend to do that nor trying to be high and mighty like what you have just said.
It is always a possibility that expression in writing can be misconstrued and interpreted on the wrong way, or sound that way.
I hope you don't take it personally, and do read it objectively, and with the right mindset.
Your sharing is what this forum is meant for, so don't have the wrong idea that I'm out to say you are right or wrong, or put you down.
What I was simply pointing out is that every child is different, and having spoken with different parents who have been to KKH for diagnosis, and given professional and/or expert advice, it is always good to look at the problem from the various possibility, root cause and not be too narrow focus, or conclude too hastily.
Maybe that is where you are interpreting it as putting you down, and saying you are wrong. NO, at no time, was that my intention, and there is no right and wrong in this case as what you have pointed out, sharing of experience.
The root cause and effective method has been mentioned before, and I don't intend to repeat it again, so do read it in an objective way, and you can find the answers in the previous post. And definitely, not here to debate or claim to be the expert, or the high and mighty you made it out to be.
This forum is for sharing, so do continue to share, and writing sometimes can't explain things as clearly as face to face, so do give the benefit of the doubt.
