Books that helped me tremendously were "What Babies Say Before They Can Talk : The Nine Signals Infants Use to Express Their Feelings" by Paul Holinger, Kalia Doner and "Playful Parenting" by Lawrence J. Cohen.

Don't be mislead by the title: the first book is not purely for infants - the principles described there helped me with my husband, with my friends, and, of course, with my almost 2 year old. The first book is more "what you are trying to achieve", and Playful parenting is more "how to get there". I keep rereading parts of both.

A recommendation by Amy Makice from PositiveParenting-Discipline:

"For a 2 yr old, the book that was most helpful to me was "The Emotional Life of the Toddler" by Alicia Lieberman. It didn't have tools in it for PD, but it helped me imagine what it was like to be a toddler- the frustrations, the fears, etc. It increased my empathy, which in turn, made it easier (though no bowl of cherries) to be patient and apply PD. Mine is dog-eared from re-reading each time I have toddler frustrations : )
