The ethics of blogging about children?

So we’ve I’ve moved our website to a new host, and reinstalled the blogging software (wordpress). So the blog works again (and someday it might be pretty again, but don’t hold your breath on that one).

And everytime I sit down to write a post that involves the kiddo, I pause. What are the ethical implications of blogging about my child? What topics are off limits? What level of privacy do I owe her?
