Prepare to LOL! In an age of sanctimonious parenting – where strangers are more than willing to give you guidance on raising your tots – mama sometimes needs to take a step back and laugh at the whole matter. Even before it's upcoming October release, Go the F**k to Sleep ($10) has become an overnight hit with sleep-deprived parents. The NSFW book, written by novelist Adam Mansbach, takes the rhyming form of the hundreds of books we read to our tots before bed, but is filled with the thoughts that only enter the minds of parents who just can't bare to read "just one more book" and get "one more sip of water." Check out five more cheeky books, only parents could appreciate!
