Here is a list of 20 Do's and 20 Don't from Mem Fox. I don't agree with some of them, but for the most part, ... excellent advise! Also... the last Don't cracks me up. ... it's a classic it's funny cause it's true. (only from people who aren't really into children's picture books of course. that counts you out because you obviously are, ... since you are reading this blog) :)
Also check out the rest of Mem's site where it came from, for lots of other very helpful tips.
