Precious Little Sleep by Alexis Dubief

If you only read one book about baby sleep, make it this one. Dubief writes with the dark humor of a parent who has been through it and the precision of someone who has actually read the research. She covers every sleep method from gentle to cry-it-out without judgment, explains the science of infant sleep cycles, and gives you a realistic plan. It is the sleep book for parents who are too tired to read a long sleep book.
