It’s an expectation and a sacrifice. By having kids you made the choice to make some sacrifices.
In the definition of sacrifice there is no provision for how much you wanted to make said sacrifice or what the motivation was. Simply that you gave one thing up for another thing you found more important.
sacrifice /săk′rə-fīs″/ noun The act of giving up something highly valued for the sake of something else considered to have a greater value or claim. “Social activism often involves tremendous sacrifice.”
Yes I understand this is coming from people who feel (probably rightly) that their parents weren’t good parents and didn’t do enough for them, and which may have said the things you mention.
But even taking all of that as true, those parents, as bad as they may have been, still made sacrifices for their kids. I agree that this is a horrible thing to hang over their heads, but it doesn’t make it untrue either.
I also agree you are signing up for this usually thankless job and should be ready for that. But that also doesn’t negate the fact that you are making some sacrifices to be a parent.
