Are you having a boy? If so, you'll want to be aware of the most significant trend going on right now in terms of baby boy names: the '-ayden' craze.

How prevalent is this trend? Last year, 37 of the 1,000 most popular baby boy names ended in either '-ayden' or one of its variants. Here are those names -- all of them -- grouped by type and ordered by popularity:

• 28,528 baby boys named either Aiden, Aidan, Ayden, Aden, Adan, Aydan, Aydin, Aedan or Aidyn


• 18,254 babies named either Jayden, Jaden, Jaiden, Jadon, Jaydon, Jaeden, Jadyn or Jaydin


• 15,928 babies named Caden, Kaden, Cayden, Kayden, Kaiden, Caiden, Kadin, Kaeden or Kadyn


• 11,646 babies named either Brayden, Braden, Braeden, Braydon, Braiden, Bradyn or Braedon


• 6,843 babies named either Hayden, Haden or Haiden


• 224 babies named Zayden

The total? A whopping 81,423 babies. (And this number doesn't even take into account all of the less common variants that didn't make the top 1,000 list.)

If we assume that males made up half of last year's 4.2 million births, then approximately 3.9% (or about 1 out of every 25) of the baby boys born last year were given an '-ayden' name. I'd say that's about one per classroom, maybe more.

And, while this is a decidedly male trend, several '-ayden' names are chosen regularly for females as well:

• 5,033 baby girls named either Jayden, Jadyn, Jaden, Jaiden or Jaidyn


• 754 babies named Hayden


• 457 babies named Kayden

This usage for girls isn't quite on the same scale, though: 6,244 vs. 81,423 is roughly equivalent to 1 girl for every 13 boys.

So what does all this mean -- should you be considering an '-ayden' name for your baby boy?

Well, it depends on what you're looking for. If you want a modern-sounding name that offers a slew of spelling possibilities, an '-ayden' name may be for you. If, on the other hand, you want to avoid trendiness, you may want to steer clear of '-ayden' names in all their various forms for at least the next few years.
