I have to say that I have some love for it, because back when I was pregnant with my son in 1986, I considered
Caitlin if it was a girl. As much as I criticize people for not knowing/not caring about a name's popularity, I have to admit that I was unaware at that time that
Caitlin had entered the top hundred the year before. And I was completely unaware that the most popular spelling variant,
Katelyn, even existed. The two spellings combined add up to a greater level of popularity than looking at the statistics for each separately indicates.
So of course it wasn't a girl and I had a feeling it wouldn't be, and when I gave birth to my son we still hadn't definitely decided on a girl's name. I like to think we wouldn't have chosen
Caitlin if it had been a girl, as I'd be cringing about that now. (Yes, I would. My sister has a sixteen-year-old daughter named
Kaylin and she cringes about her name.)
But I'd be cringing because
Caitlin /
Katelyn / other spelling variants are so ubiquitous and now dated, not because of the name itself. I liked it enough to consider it then, so I have to think my negative reaction to the name now is only because of the ubiquity already mentioned, and that somewhere buried underneath that, I still like the name.
I've never thought of a nickname for it. I suppose I like
Cait.
Caitlin is the only spelling I'd use.
