No, the 3-syllable middle name is a nod to my son's father (since he's getting my 1-syllable surname) and I'm pretty locked into that. So
Shug would truly just be a pet name, like I'm Auntie
Kitty in only that context. But, I appreciate your caution of this little boy nickname accidentally sticking around ... Since this is not a naming convention in my family at all, I don't really know what to expect.
I want
Enitan to be his name, and what he's called, I'm just trying to come up with a solution for the two times a year he'll be with his cousins.
Eitan is 14 years old, so the age gap should mean it's much less of an issue in the not too distant future.
