The Hike it Baby club/movement is very lovely, but I found the book disappointing, and more like "a list of doable trails for baby-havers in major US hiking areas." Which seemed to just mean short hikes, from what I could tell reading. Next time I'm planning a hiking trip I'm not sure I'd consult this over conventional local hiking guidebooks or the internet in general, which almost always cover short, easy hikes because they are popular with everyone.
The most valuable content was non-trail content, like "10 Essentials for Backpacking with Babies," "Bottle Feeding on Trail: Always Be Prepared" (I'd never thought about the difficult logistics of hiking with pumped breastmilk) and "Hiking Safety During Hunting Season," but all this valuable content was relegated to side bars dispersed randomly throughout the book. The vignettes about families in the Hike it Baby movement were also very inspiring and nice to read. I'd have appreciated a smaller book just dedicated to this sort of material, without any trail information, which is easily found elsewhere, unlike methods for merging the difficult particulars of life with child with hiking.
Certainly worth a pick up at the library, and if you're a baby-haver and a hiker you should certainly check out the website to see if you can meet some fellow travelers, but not one I think I'd ever come back to for planning hikes.
My copy of this book was free from the publisher for the purposes of review.
