Hm, the question is – balanced in what way.

My ILE-Ti E7 brother has some kind of ADHD condition. Nothing too severe, but it used to be very noticeable when he was really young.
Some doctors have suggested for him to take medication for that in the past. My ESE-Si mother refused to give him any. (I am glad she did.)

As he has been growing up, his condition seems to have been improving gradually. He is much calmer now in comparison to several years ago. No one is exactly sure, why.
Perhaps it truly boils down to the fact he could grow up with two Si strong parents (ESE-Si, LSE-Si).

The only downside: He still does not know how to make himself a sandwich or eat anything else besides cereal when our ESE mother does not bring him proper food, or he is not eating out at some (fast food) restaurant.

But hey, the same problem might have been the case without Si parents.
