When our first child was due, in 1997, the date of his expected birth (though not of his actual birth) was the Second Sunday of Easter. Even though it's not his birthday, it's a day that has gained added personal significance from this fact. The day is also known as Quasimodo Sunday from the first words of the introit, "quasi modo" ("after the fashion of" or "like"):
Quasi modo geniti infantes, alleluia: rationabiles, sine dolo lac concupiscite, alleluia, alleluia, alleluia.
Like newborn babes, alleluia, desire the rational milk without guile, alleluia, alleluia, alleluia.
Or, as the King James translates it: As newborn babes, desire the sincere milk of the word.
When I mentioned the due date to my old tutor he exclaimed with delight, "Why, then you can call him Quasimodo!" It's not a suggestion we entertained seriously, but now that I've told our son about it he seems disappointed at the missed opportunity.
