based on what you know about the immaturity of the amygdala in early childhood, what is a likely experience that many young children have?

It would be 23 beats per second

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. 

I'd say 8. i'd u don't so what u should u don't get what u want.
