"The No-Cry Sleep Solution For Toddlers and Preschoolers" - I just started reading it and am SO glad I picked it up. There is a lot of really good info in it, and some surprising study results. Since I haven't read through the entire book yet to give a complete review, there are some great reviews at amazon: http://www.amazon.com/exec/obidos/tg...glance&s=books
She addresses the family bed, breastfeeding toddlers and other situations that most sleep books don't address (or if they do make you feel like a bad parent). Plus it is geared towards toddlers and preschoolers, and done so in a supportive, non-judgemental way.
HTH!
