Kids don't ask to be born.
Not every parent asked to become a parent; not every parent retrospectively wanted children.
Not every parent who claims to love and respect their progeny acts in line with that assertion.
It's okay to not want kids. It's okay to not be physically and emotionally comfortable around kids.
It's okay to feel irritated with how some parents make being a parent their whole personality, or describe it as a sacrifice (it is in many ways), or act as if they should be rewarded for doing so.

If you are a parent (by choice, I hope, for everyone's sake), then you are entitled to ALL support you need to sustainably raise a whole-ass human from scratch or from adoption or otherwise.
Caretaking is an art, a science, an act of selfless love, and an ideal of connection with other living beings.
Not everyone is or should feel compelled to perform caring tasks for others.
There is nothing wrong with saying "no".
