About Kaidyn
The popular Aiden has spawned a legion of offshoots used mostly for boys but sometimes for girls too: Brayden, Caden, Kayden, Zaiden and so on. While it is now predominantly used on boys, back in the late 2000s and early 2010s, it was used more equally on girls. In a recent count, the name has fallen out of favor, with only 14 girls receiving the name in 2023.
Pronounced KAY-din.
As of October 2026, Kaidyn ranked #9144 in US births in 2025 SSA, peaked at #1924 in 2009.
Editor's take: The name Kaidyn is a girl's name meaning "round or barrel".
