@MinteeFresh Kids don’t necessarily mess with names. I’ve got two boys (one nearly 20) with two syllable names. Their friends have never shortened them in any way.
I shorten the youngest’s name (to the first syllable). But his friends don’t. None of them. It surprises me, but they just don’t.
DSD has a 4 syllable name (which is such a mouthful, I just can’t believe it’s such a popular name) and no one shortens it either. They probably never will (based on my experience of older girls with the same name). I’d shorten it if it were up to me.
I never shorten my (truly horrible - thanks parents) 2 syllable name because there are literally no shortenings that aren’t outright objectionable. The only time anyone has tried to nickname based on it (while I was a university), the guy quickly concluded that it was impossible to do it without being insulting in very dubious taste.
DH shortens his 2 syllable name because people often assume he’s a woman from the full version these days (it’s one of those boys names that people increasingly give to girls). His parents didn’t anticipate that back in the late 70s.
Conversely, my ex’s family have always shortened his name. He hated it so he started going by the full version when he went to university. Occasionally some of his friends will use a completely different, stupid, shortening to the one his family use but not often.
The things is: you just can’t know what’ll happen with the name you choose. It’s not within your control.
But if there is an obvious nickname you hate or (worse) your spouse has already said they’ll shorten it to something you hate, then it’s probably best to avoid that name entirely.
