Wouldn't the employees of the day care be able to be considered as "child raiser" if I follow the meaning of the words?

No, because child care (aka day care) is temporary and optional. A person who is raising a child has taken responsibility for them through their childhood—metaphorically “raising” them up into adulthood.

You're the only one in this thread not attaching the same connotations of "child raiser" to "parent" and considering one lesser than the other. I don't know what's more insulting, being called a child raiser, or considering child raiser to be off-brand parent rather than a generalization of the term.

"No man goes into education to be called 'instructor', they're 'teachers'."

"No woman goes into CS to be called 'coder', they're 'developers'."

Some children are raised by grandparents, aunts or uncles, siblings, etc.

There are plenty of “child raisers” who provide more care than a daycare and less than a parent.

And since we’re being technically correct, raising a child is always optional (even for the parent).

I agree. That’s why I said child raisers have “taken responsibility.” I could have also said “accepted responsibility.”

I wouldn’t consider a parent who opts out of raising their child to be a child raiser.
