I did some more research, and found that Leapling was a term made up by some 1992 baby's mom for her book. Ah, how existential.
I am gunning for the term Leaple. It's a French surname, but is not an English word. It is a contraction of Leap and People-our birthdays make us special, but we are just people. Leaple works for me! Here's to getting it in Wikipedia.
