would rate 100 out of 5, Order First period kit and Period Guide for Son
I ordered it for my son who is 8 years old. As my daughter got her periods, I wanted him to educate. We have shared little information about periods already but your books helped us to educate in a structured way. Also as its story format, it also helps him grasp better. Fun thing is after looking at all food items, my son asked me when he will get periods :)
