That phrase absolutely jumped out at this word-lover too: "sensory
nourishment"

This paper really sums it all up so nicely: "Humans carried their young for
99% of their evolutionary history because the exterogestate foetus, unlike
other infant primates, lacks the neurological development required to cling
to the mother after birth.  [I]t has been argued that a diversity of
vestibular stimulation significantly improves an infant's motor development
and ability to learn, and that the more an infant's brain is showered with
sensory input, the more likely it is to reach the upper limits of
intellectual potential.  [W]e have not considered that the hunger for
sensory nourishment (e.g., diverse vestibular, touch, proprioceptive and
visual input) is biologically driven and may cause distress in an infant
comparable to the distress of hunger for food, resulting is excessive
crying." (p. 890' citation omitted).

Or, as Nils Bergman might tweet this:  "Brain cells that fire together wire
together."
