is Kaylie and Katie pretty much the same ?

Well I named my daughter Kaylie and she has her cousin name Katie I'm kind off regretting that I named her something similar to her cousin . When I named her didn't really pop in my head so I'm like -___ - now guess I can't really complain now . I guess I'm second guessing it when you have some of my sister in laws kinda say "you should of picked a different name " What are your thoughts?
