We have been engaged for four years in the researches of raising a carefree child in Nature, considering that a child can live a carefree life if we, who take care of it, properly help it live favorably influenced by Nature. As a result of the researches, we confirmed that child's various experiences in Nature encourage it to develop carefree mind and desire to face things, and more than that, the experiences have a power to improve protectors' attitude to child and the way home should be.
In this paper, we summarized the researches, especially focusing the third year's theme: contrivances of how to encourage child to live in natural objects close by in order to cultivate the germ of interests and thinking faculty in it.
