Doing for themselves specifically meant permitting newly weaned infants to choose how much or how little to eat of 33 available foodstuffs. As she emphasized to her Quebec audience, no adult was allowed even to hint to the children what might be a proper choice or portion amount. “The nurses' orders were to sit quietly by, spoon in hand, and make no motion,” she said.
Accordingly, Davis devised the experiment to let children do for themselves because she suspected that children's bodies instinctively “knew best” what the individual child should eat. Her intellectual model, a view that would later be called “the wisdom of the body,” likened a child's instinctive appetite to the way various autonomic body systems effortlessly adjust themselves to compensate for external challenges — think of sweating on a hot day, and breathing faster when you start to run.
Initially, it seemed that this conceit didn't apply to Davis's test children and their food preferences. None of the eat-what-and-how-much-of-what-you-want infants had the same diet on any given day, week or month. “Every diet differed from every other diet, 15 different patterns of taste being presented, and not one diet was the predominantly cereal-and-milk diet, with smaller supplements of fruit, eggs and meat, that is commonly thought proper for this age,” she told her Montréal audience.
Yet, she and others later saw that the infants' fanatical heterodoxy turned into what appeared to be 15 uniformly well-nourished, healthy children.
How could eating drastically different diets achieve uniform health and nutritional balance? Body wisdom was the only likely explanation Davis concluded. “Such successful juggling and balancing of the more than 30 nutritional essentials that exist in mixed and different proportions in the foods from which they must be derived suggests at once the existence of some innate, automatic mechanism for its accomplishment.”
However, this does not mean infants should not be taught what to eat.
The foods she offered the children were varied, but all were generally
thought to be healthy. Their intrinsic goodness meant that it would
have been difficult for her small charges to veer too far from the
“Errors the children's appetites must have made — they are inherent in
any trial-and-error method — but the errors with such a food list were
too trivial and too easily compensated for to be of importance or even
to be detected.” The key thing was to provide healthy food and let
children eat as much or as little of it as they wanted.
“The results of the experiment, then: Leave the selection of the foods
to be made available to young children in the hands of their elders,
where everyone has always known it belongs,” she told her peers in
While an interesting double-hinged interpretation of her results, it
was, Davis recognized, more a comforting argument than a true
demonstration of the limitations of baby body wisdom. She did not
present her little ones with a foolproof diet, just a
The study is lacking statistics, graphs and all that.
All that Davis did was to tell what she found. There are absolutely no graphs, no charts, no individual breakdowns of any sorts for any of the children. It's a summary paper of an Everest of data with next-to-no data in it.
