They evolved together."
How can you have a child before you have a parent (at least physically)? If you are talking about having a parent (first) and then a child (second) and that within that species they "evolve," I have no problem with that. Except that children are not always like their parents. So to assume that a protective parent would have a protective child is a bad assumption.

I did not write the question you quoted. I wrote the answer to that question.
The original poster had noted that human infants are helpless for years. So, he asked:
"The human infant can not fend for itself for many years after birth. Did the parent evolve before the child?"
In other words, the original poster wanted to know which came first, a totally helpless offspring or a protective parent that will protect the infant for a long time period after birth.
The answer is neither.
Such a combination of traits take an extremely long time to develop and both traits must develop together resulting, over tens of thousands of years, with a combination of progressively more protective mothers in conjunction with progressively more dependent offspring.
Except that children are not always like their parents. So to assume that a protective parent would have a protective child is a bad assumption.
When I answered that poster, I was not speaking about "Good Human Mother" vs "Bad Human Mother". I was speaking about salmon or sea turtle mothers who give zero post-natal maternal care to self-sufficient offsping that are own their own from the moment of birth vs bird, bear or human mothers that given extensive maternal care to totally helpless newborns.
In Nature there is a term for a totally helpless newborn (as in the case of birds or bears or humans) that are paired with a mother that gives zero post-natal maternal care (as in the case of salmon and sea turtles).
That term is: "Dead".
Such a throwback trait in the mother "selected against" with extreme prejudice in the case of her genetic offspring.
