What is spiritual childhood?

"Spiritual childhood is neither a method nor a devotion. It does not follow any one particular exercise, exterior attitude, or type of language. It adapts itself to all settings and conditions of life. It is at once something more and something less than all these things: it is the realization of an attitude of soul. It 'consists in a dispostion of heart that makes us little and humble in God's arms, conscious of our weakness and confident to the point of audacity in his goodness as Father.' (Last Conversations, p. 129)."
