Liedloff, no doubt, wrote this book as a much needed radical diversion from the 'modern' methods of bringing up babies in the 60s and 70s.
Unfortunately, it reads like she is shouting - and she is shouting out opinionated and unfounded socio-waffle (for want of a better word). This may have fallen on hungry ears in the 70s, but not so today.
One can't help but feeling she sees only positive things in the way of the Yequana (a tropical rain forest tribe in Venezuela) and only negative in the Western/civilised culture. For example, when a Yequana child is injured, she praises the mother's coolness - why not see this as disregard for the child's well-being? She attempts to starkly contrast the two cultures, but not all babies/parents are as she describes and so paints a very false picture by presuming to know how we are and how we see ourselves (one wonders if she sees herself like this).
There are, of course, vast cultural differences between the Yequana and the West, but many of the Yequana's child-caring methods find easy parallels with Western upbringing: she describes in detail the happy children of the Yequana - but if we change the canoes for bicycles and the bow and arrows for footballs, it is not much different from a description of children in the West.
Many parts of the book are rather hard to accept: she criticises praise; states that children have (fatal) accidents simply because that is what adults expect of them (a parent says 'you're going to drop that plate' and the child drops the plate); and shows a complete misunderstanding of homosexuality which could easily be seen as homophobic! She even goes on to explain that a child will release pent up energy via masturbation (is she writing about babies or teenagers?).
She writes 'if one wants to know what is correct for any species, one must know the inherent expectations of that species'. And from reading the book, one feels that Liedloff believes she knows!
Far too often, the books reads as if written by a psychotherapist looking for one thing which causes all problems: the deprivation of the 'in-arms' experience. She presumes that carrying babies is the reason for the differences between the Yequana and civilised culture; that when not deprived of expected experiences one has a happy folk; that Easterners are less deprived (of in-arms experience) than the average Westerner and therefore have more serenity! She is believes that the Yequana live in real joy but that we (Westerners) do not. All of this is completely unfounded. Nevertheless, she is convinced her continuum theory is best - and yet she can't (or won't) explain why one group of Indians is peaceful and another is aggressive.
She does realise that it is unrealistic to change our culture to another - but unfortunately only because we are the 'wrong' sort of people. There is a course a vastly differently social structure: the 'civilised' world is lacking the advantages of tribal unity - we have only compact family-focused groups which are often not even together - and this causes deprivation for both children and parents.
But what is the central message of the book?
She is against overprotecting a child but all for keeping it close and loved and, primarily, in doing what feels right or natural or instinctive. In essence: hold your baby. There is some good practical advice in the last chapter and one can happily surmise that a child is part of our life and should not be separated from it. But this sound advice is so heavily burdened with the rest of the book, that it is hard to appreciate.
