Absolutely forbid them to open their mouths unless to put food in it.
Just kidding. I may or may not have done that this morning.
Actually, I thought I'd share something about one of the essential oils I use. My oldest son, is a typical seven year old boy in that he absolutely hates to sit still. The boy quite literally hits the ground running in the morning. He has non-stop energy. Unfortunately, this also means that in school, he has a hard time sitting still and focussing on what he's supposed to be doing. He also is one of the most social kids I know. He loves people. He loves making friends. He loves hearing the sound of his own voice.
Thankfully his teachers have been pretty understanding about who he is, but that doesn't make him exempt from the rules. So, it's been a struggle to not only keep him in his seat, but to keep him quiet and focussed.
We were at our wits end. He's a good kid, and he really wants to do the right thing, but he has a hard time controlling himself. I decided to try "In Tune", DoTerra's focus blend.
