This is true. if you get drunk a million times a day, this is really bad on your liver. your liver can suffer severe damage from overdose of alcohol. it can be life threatening.

If it's a smaller child or infant, place one on the middle of the chest and on the child's back. (if it is a bigger child with enough room for two, place one on the upper right/your left of the chest, and one on the lower left/your right) the pads should never touch each other.
