Cry it out is unnatural in my very humble opinion. It's a solution designed to get mothers back to work in a nuclear family. Children are a lot of work when little. It is extremely hard on the mother. There is also the big breast feeding mania - which while good will really not help the mother get back to work faster. I think we as a society need to make up our minds. Do we want more happy children and happy parents in a nuclear family or do we want mothers and fathers back to work as fast as possible with no regard to the children? It seems we're settling for the latter and making some bullshit pseudo-analysis that its the former.
