Ask Moxie (http://moxie.blogs.com/askmoxie/), for parenting Q&A from a sensible person. If you have a non-sleeper and want to feel less alone, check out her posts on sleep regressions. She's also got a great series on preventing post-partum depression.
Dr. Sears' web site(http://www.askdrsears.com), especially the medical section. I love the concise descriptions of childhood illnesses, and how they clearly articulate what symptoms are 'wait and see,' 'call the doctor,' and 'take that kid to the ER, stat.' There are also useful dosage charts by weight for most common over-the-counter medicines.
Berkeley Parents Network (http://parents.berkeley.edu/) This is kind of my dream for what Parents @ Duke's online empire could someday be. Until we have 18,000 members and 10-12 weekly email newsletters, this is a great place to look for archived advice from parents in an academic context not unlike ours (questions like, "Is it possible to write a dissertation with a baby in the house? How?")
What I haven't found is my ideal website for local parenting stuff, activities, etc. There's Carolina Parent (http://www.carolinaparent.com/) and they have an events calendar that's pretty useful, but I'd love to find something less corporate and more funky.
Do you have a favorite parenting web site, or blog? I'd love to have more on my list of
