Reading can be fun.
Format: Hardcover
I particularly like Munro Leaf's book on reading, which was written for young children to either read or be read to. The logic of choosing good things to read to develop the mind ( as compared to exercise for the body to develop) is a basic concept in the book. The stick figures are fun and mirror the text well.

Rather dull.
Format: Hardcover
It seems dull and preachy now but may have been fine when it was written (many moons ago). However, not a patch on the magnificent (at least in my memory as a child) Ferdinand The Bull - still a favourite of mine (am I really that old?) I've recently bought many copies for a number of two-year-old children.
