I know we have had a spate of bebeh birthings in the past short while, so I thought I'd recommend one of my favorite baby medical books. I didn't get this one until I had my second, and I know if I'd had it when my first was tiny it would have saved me a lot of worrying in the middle of the night and unnecessary trips to the doctor.
This is, hands-down, one of the most useful books I have ever read. It saves you from the fear-mongering dire death warnings that come from most websites when you Google "child's rash" or "baby vomiting" or "toddler fell and hit his head." Dr. Zibners is an ER pediatrician and explains what is and (more importantly) what isn't cause for concern. It's like having a pediatrician on your bookshelf (or in your Kindle).
*I have no connections to the author or publisher, but I did think of this today because I looked up something that my youngest has which I've never dealt with before and was immediately relieved to find out that no, he isn't going to die. ;)
