What should my sister call her Triplets?

I strongly dislike matchy matchy names, they are individual people, not part of a matching set of dolls, they already share the same birthday, age, grade, and will forever be known as "the triplets", at least give them their own initials. Jayne and Jayde? At least change more then one letter so the poor kids can have some kind of individuality. These are all also cutesy names that wont age well, nicknames, try something more mature, like Mia Jayde, Jane (no reason to misspell it) Elizabeth, and Charlotte (lottie for short) Maci.
