Both of these names are so common among my age group, with all spellings you can possibly think of (
Even one Haliegh, not a typo). Seriously, these names are up there with
Emily,
Madison, and
Brianna! Regardless, I don't care for the
Hayley and
Kayley spellings of these names; I like
Haley,
Haleigh, and
Hailey instead of
Hayley, and Cailey,
Cayley, Cayleigh,
Kayleigh, and
Kaylee instead of
Kayley. To both names, I prefer
Makayla, which is one of my favorite girl names (also, uber common in my age group). However, I don't think that
Hayley or
Kayley are horrible spellings, just not my first choice.
