When we had just had our fourth child, some b****y doctor tried to tell me that I shouldn't beget any more. I felt like precipitating him down the stairs. But at that time I lacked the manly resolution that comes of being a Proper Catholic. So I dithered.
If Alberto Gasparri were to tell me that the ideal size for a family is three, I think, being now in Full Communion, I would loyally take the wise advice of the Sovereign Pontiff, and instantly thump him before I thought better of it.
