My child loves this collection he knows by heart now. A different material to each page of fun themes and simple but colorful drawings! This is perfect for awakening the child learning to touch, that teaches the difference in textures! I began this collection in four months of my child and it shows because now opening a book, he seeks his own material! It is perfect for little ones with the help of parents. Small and thick format, convenient for the child who can use it alone.
