[name]Do[/name] you think people (who aren’t name nerds) would even notice?
No. I think noticing that kind of thing would make someone a name nerd, even if they had never heard the term. 
Three of my kids have 2-2-2 names. It doesn’t bother me. The other names (3-3-2, 3-2-2) probably do flow better, but I still find the 2-2-2 appealing in its own way. It sounds very solid to me.
I don’t think people will notice, as long as the names flow together well, both on paper and when said outloud.
My husband is a 2-2-2, and I only noticed it now, when I read your post and tried to think of examples that I know! So, no, if the names sound good together, I don’t think people will pick it up in a negative way…
Yeah. I got 3-2-2 strictly by luck, but my parents and both of my two dearest friends are all 2-2-2, I never really thought about it til I read [name]Pam[/name] and [name]Linda[/name]'s book, their names sound all just fine. I do think that when it’s mixed up it’s an extra nice touch, but, I don’t think there’s anything inherently bad about 2-2-2 at all.
I think name nerds pick up on a lot more than regular folk…
It definitely depends upon the names though. I knew guys named [name]Luke[/name] [name]Paul[/name] [name]Smith[/name] and [name]John[/name] [name]Dean[/name] [name]Smith[/name] and to me they sound so choppy and awkward but no one else ever notices! A girl I knew was called [name]Lauren[/name] [name]Rachael[/name] [name]Harper[/name] and for me 2-2-2 names don’t flow very well but that isn’t to say they are bad names.
I tend to be seriously picky with names being a name nerd and all and things like same letter first names, rhyming or alliterative names or overly matchy names aren’t my style at all but some of my friends are like “ah, that’s cute” to a set of twins named [name]Noah[/name] & [name]Norah[/name] or sisters named [name]Liora[/name] & [name]Aurora[/name]…
So my answer is they probably won’t notice it like most of us name nerds do so I wouldn’t let it bother you.
No, I don’t think they would notice at all… my mom and I both have 2-2-2 syllable flow. Then again, the emphasis on both of our MNs ([name]Arlene[/name] and [name]Marie[/name]) are on the second syllable, so I think that breaks it up a little.
I plan on using two MNs for my kids, though, and 2-2-2-2 is where I draw the line, haha. It’s just too monotonous for me! Although I do have [name]Charlotte[/name] [name]Eden[/name] [name]Winter[/name]/[name]Ruby[/name] [name]Richards[/name] on my list and that is 2-2-2-2 and I can’t seem to let her go… it’s nice to mix it up, but I don’t think it’s the end of the world if you don’t. 
My husband has a 2-2-2 name and I’ve never even really noticed it. I don’t think anyone (beyond a huge name nerd) is going to notice it.
My son’s name is 2-2-1, and at first I was concerned about choosing a 2-2, but now I just think that was ridiculous. He’s [name]Simon[/name] [name]Daniel[/name], and it flows well (to my ear, anyway!), and we love it! Go with what you like, and people definitely won’t even think about number of syllables.
I think I’ve written about this because all my kids are 2-2s (fn and ln) and the youngest is 2-2-2. I [name]DO[/name] think that if you have a 2 syllable last name, a 3-1-2 or 1-3-2 rhythm is inherently more pleasing. But I didn’t think of this with my own children!!! So take it for what it’s worth…
You know what, I never even noticed it but I grew up with a 3-3-3 name until I married and am now 3-3-2. So I guess if I’d thought about it I would have realized that I didn’t even notice it!! My daughter is 3-3-2. I think I’m going to let go of this particular neurosis as we attempt to find a name. Luckily I have a whole stack of OTHER neurotic things that can X all the names off the list…
