I work in human developmental research and have never heard or read anybody make such claims that you consider "bog standard child development science", and some of what you say are definitely not supported by the current understanding of human development.
For example
> child language development milestones that are waymarked by age down to the month
is totally false. It is quite known that developmental milestones are acquired by children in different times and even in different orders and sequences. This "down to the month" is pure non-sense for most of the milestones.
Young children are better served to be guided by their own curiosity, interest and exploration drives and which parents feed with variable inputs and building upon, rather than by anxious parents feeding them with whatever terabytes of exploitation-intended information they think is gonna "serve to maximize IQ".
Yes, reading to kids in certain ways (using numbers/spatial relationships/theory of mind stuff/interactively) has been found in some studies to correlate with certain outcomes but there is nothing to suggest a totally linear relationship such that talking to a kid 24/7 since the womb is gonna produce the next Einstein.
