Too bad! Yet it was a good start: the deck to explain the blended family is clever. But the end, what a mess! Children specimen and those with two dads "exist" !!! Every child is born a man and a woman, and it is important to explain, even if it is high in different ways, under penalty of ruining his psyche. You can not have two dads !!!! As to test children, swing it in a children's book, without further explanation, then that is a book available in the media libraries and schools, and therefore likely to be read by children alone is dangerous and may disturb children.
