No bucket of stones.
Irresponsibility is just that. Neither Brady nor the lady deny their promiscuous liaison, nor the real likelihood that it is Brady's child.
And while it is certainly good that there is no abortion of the child, it is better if the poor kid gets to live with his very own loving Mom & Dad. The statistics are clear on that.
While there is virtue handling mistakes with mercy and compassion, there is no virtue in pretending they don't exist and never existed.
I too prefer both parents be in the house etc.
But I know a few women who have had children and are not married to now or maybe never were married to the father.
If it can be worked out you can parent a child together without being together.
