Excellent for an adult beginner, but not that obvious to a novice child

This is an excellent book for an adult who says "well, I'll learn chess in a fun way, without complexes." Because it is short (128 p.), Progressive, with small fun designs.
To say that this is the ideal with a child, not so sure!
On the one hand, the book works by parts, which are in fact as many lessons.
Part 1 begins with "room Doe has the right to do this, that, but not this."
Then, handling exercises of the room (interesting).
But in the second part, the author discusses on the value of coins, passing well above the head of a child aged 5-6 (3 equivalencies pawns 1 = crazy). And full of tactical considerations ("the madman is a long-range weapon, the jumper is short") which are also too abstract for a child.
From the third part, the book goes fast, very fast, but it's almost too full. Taking the way, do lady, the promotion, the term "related to black, to white line" everywhere ... So many things to remember!
From the fourth part, an adult begins to scratch the forehead (the difference between making "pat" and make "mat", not obvious) and an 8 year old picks up, IMHO.
The fifth section presents the most classic openings, fork and all the tricks and plays with all parts of the board.
In summary, this is an ideal book for the general complete beginner, not a complete novice child (I would not say the same for a small club player).
With a child of 5-6 years, we must bone up before the lesson, prepare small games on the board, and propose form of riddles.
So, for a real playful interaction between the child and failures, even more progressive than that, I recommend Vive failures!. That book is designed with the situation sheets, we put the child in game situation, without complicated vocabulary, always with the idea to play, play play. This is from a book for teachers, but it seems written especially towards adults in general who seek to love chess, without frightening the child.
