Children's books, adult infantilization

There's a substantial literature on the Jungian aspects of children's books, how it gives them all these nice archetypes and whatnot. But what about what the books do to us, the readers? They are, on the one hand, nice and soothing after a long day of this, that and -- all too frequently -- the other. But might they also dim our brains with little lambs and nice green rolling hills and windmills and all that? Might they not leave us too with the erroneous impression that life might be like that, only to find us collared with a forearm as we cross the office threshhold?

Anyway, they're so cute. Especially the ones about bunnies.
