Query: Sickens me-where is the research?

I am appalled at the tone of this book, that children are sucha nuisance. Nurturing children in the early years by allowing them toTRUST their parents, not cry it out, is the key to alot of this country's problems. If you want RESEARCH on a nurturing parenting approach, read "Attachment Parenting" by Katie Allison Granju. Babywise is appalling.
