While we were staying in Japan, my kids did not have to take any meds. They were not hyper at all. My parents told me not to give my kids any pills...
They ate sweets...a lot of icecreams, cakes, cookies and more. But they did not go wild.
When we got back to U.S., it proved to me that we have much more sugar in everything. My kids started acting wild again after they ate a few cookies and drink a cup of soda.
Wow, what else could it be?
I started re-think about what I had to give them from now on.
