H.B.
I have read and used the advice from The No-Cry Sleep Solution, with great success. I really love her approach, including helping you, the parent, evaluate the needs and desires of the family. She also has very sound information about what is *normal* and *healthy* for children at various ages. I find the range of recommendations and "solutions" to be quite handy in addressing the various situations a parent might find herself in.
I hope it's helpful for you, as well!
