When learning of the word, very useful book. I have long thought that they did not serve because my son did not repeat the words that we learned together. Only today at 2 1/2 years I am surprised to hear my son say by heart the words and situations of these little books. He even associates it sees situations of everyday life, and this is in my opinion, the greatest asset of this collection! Second great advantage: the resistance. May be left without problems reach of small children. Can be reused for siblings.
