ML, dun worry. last time doctor said the same thing. My boy had blood infection during his stay in nicu,and there was a patch of scar in his brain. The doctor told us it could affect his development. But luckily, we didn't see that has any impact on him. He is in p1 now, and he is doing very well in his studies, exceling some of his pals. Dun worry too much. Let nature takes its course.
