I wasn't trying to argue the pros and cons of milk and dairy consumption, I was trying to ridicule the argument that fast growth of new born mamals is due to milk consumption and your how the doctor arrived to that conclusion.
New borns are "programmed" to grow fast. They do need energy to allow this growth, but consumption of milk is not the reason. There are a lot of baby humans who are dairy intolerant, they are fed with non-dairy replacements, and surprise, they grow at the same rate as other babies.
As you point out. Milk is for baby animals. Cow milk is for cows. Adult humans are neither babies nor cows.
Green vegetables are for all omni/herbivores.
