I appreciate the range of health care options in this book, from allopathy through osteopathy through herbs and nutrition, even venturing into quackery with homeopathy. :-) Sometimes I take immediate action after consulting this book, such as when my daughter's symptoms were accurately described as scarlet fever, and sometimes I continue with palliative care, as when breastfeeding a vomiting child.
The authors encourage you to examine your options, when appropriate, and when to seek immediate care such as with poisoning, shock or polio. I have never had the impression they push any method of health care over any other, but rather want the parent to have all the options. Read the introductory sections on all of the modalities they offer so you fully understand the rationale behind them. Read the home safety tips too; most are pretty obvious to parents, but there may be something you overlook; don't we all?
I'm lucky to have very healthy children so I don't need the specifics a lot, but this book is well written enough just to have on hand and read out of curiousity such as when the neighbor's child has roseola or just to tell your child what it really looks like when someone breaks a bone.
