So if you are a book reader, get Life with Toddlers. It has about 228 pages of information, and more elaboration on the technique with several more toddler issues (sleeping, bottles, etc.) It also has a chapter on developmental skills - what they should be doing at what age - so you know if what you are asking and expecting them to do is a reasonable request. We mommies forever wonder "When is the right time to teach X, Y, Z?" This list will help!
If you have no time to read (or don't like reading), no idea where to start, possibly did not have a good example of parenting growing up, and want very basic, quick answers, get ABC Guide to Discipline. It's only 80 pages, and will give you a fast start on the right track.
Hope this helps! Good luck!
