after a e-mail about a 3 year old fighting those new teethe, we definetly have to make a teetheing spray, because the sprays stop a sore mouth in about a second and that could be like a miracle for the little child fighting terriable swollen gums...a very easy formula to make, that could be used as many times per day and night as needed, even spray those hard toys they suck on, etc... the only side effect i can think of is killing germs as well!
