[name_u]Luca[/name_u]
[name_m]Dominic[/name_m] - never been a fan for some reason
[name_m]Milo[/name_m] - I think it’s cool, but have trouble picturing it on a person; probably because I don’t know any [name_m]Milo[/name_m]'s
Thank you jtay07! [name_m]Milo[/name_m] does worry me some; I’ve heard some people say it sounds like a dog name.
[name_m]Oliver[/name_m] - A true winner all the way around! It’s handsome and cute! Also, there are no expected spelling or pronunciation concerns.
[name_m]Sebastian[/name_m] - The middle part of the name “bast” is off-putting to me.
[name_m]Dominic[/name_m] - I’ve never been able to warm up to it, but it’s not bad.
[name_m]Mateo[/name_m] - Same as above
[name_u]Luca[/name_u] - Too reminiscent of a girls’ name for my taste, but I know it’s a boys’ name. Not a bad choice.
[name_m]Nicolas[/name_m] - I [name_u]LOVE[/name_u] the name! However, if he will live in an English-speaking country, I prefer the spelling [name_m]Nicholas[/name_m] to minimize misspellings.
[name_m]Milo[/name_m] - Not a big fan
My top three are: [name_m]Milo[/name_m], [name_m]Sebastian[/name_m], and [name_m]Mateo[/name_m] (note sig.)
I like [name_m]Oliver[/name_m] and [name_m]Dominic[/name_m] a lot too. All nice names-great list!
[name_m]Dominic[/name_m] and [name_m]Mateo[/name_m] are my favorites.
Agreed! I also really like these two.
All of them are good names, but I’d rank them in the following order.
[name_m]Mateo[/name_m] is my favourite by a mile!
[name_m]Oliver[/name_m]: nice, works on all ages, but maybe a bit safe?
[name_m]Sebastian[/name_m]: good strong name, and I like the jazzier [name_m]Bastian[/name_m] as a nn.
[name_m]Dominic[/name_m]: OK, a good classic name again, but not my personal taste.
[name_m]Mateo[/name_m]: like (though I prefer [name_m]Matteo[/name_m], or even [name_m]Matthias[/name_m]). It’s fun but masculine.
[name_u]Luca[/name_u]: sweet, soft and strong. One of my favourites!
[name_m]Nicolas[/name_m]: I really like it. It’s classic but not overused, and so elegant. Spelt like this the lovely nn [name_u]Nico[/name_u] is very natural.
[name_m]Milo[/name_m]: I adore [name_m]Milo[/name_m]. I think it’s a beautiful name and works on any age. [name_m]Don[/name_m]'t listen to the people who will tell you it’s a “dog name”!
Top 3: [name_m]Milo[/name_m], [name_u]Luca[/name_u], [name_m]Nicolas[/name_m]. You really do have a great list - the only two I’m not personally keen on are [name_m]Sebastian[/name_m] and [name_m]Dominic[/name_m], but to be honest that’s a personal association thing and there’s nothing at all wrong with the names themselves.
I love [name_m]Oliver[/name_m], [name_m]Sebastian[/name_m], [name_m]Mateo[/name_m], and [name_m]Milo[/name_m]
I like:
[name_m]Oliver[/name_m] - I really like this, it would be on my own list but its a bit more popular than I would like
[name_u]Luca[/name_u] - this always strikes me as stylish & has a current sound
[name_m]Milo[/name_m] - handsome & fun name
[name_m]Oliver[/name_m], [name_m]Sebastian[/name_m], [name_m]Dominic[/name_m] and [name_m]Milo[/name_m] for sure!
My favorites in order:
From your list my favorites are [name_m]Oliver[/name_m], [name_m]Dominic[/name_m], [name_m]Mateo[/name_m], and [name_m]Nicolas[/name_m].
[name_m]Sebastian[/name_m] is cute but I can not picture it on an adult male. I feel the same way about [name_u]Luca[/name_u]. And [name_m]Milo[/name_m] is the name of my friend’s dog so I will probably always associate it with an animal’s name.
[name_m]Oliver[/name_m]- I love this and i especially love the nickname Oli.
[name_m]Sebastian[/name_m]- I like this name but not as much as [name_m]Oliver[/name_m].
[name_m]Dominic[/name_m]- Very very cute but not something I would actually consider naming a child.
[name_m]Mateo[/name_m]- This is okay but I prefer [name_m]Matthias[/name_m].
[name_u]Luca[/name_u]- I love love love this.
[name_m]Nicolas[/name_m]- [name_u]Nico[/name_u] or [name_u]Nick[/name_u] are cute nicknames.
[name_m]Milo[/name_m]- I see this as being a pet name.

Favourites:
[name_m]Sebastian[/name_m] - Bash, [name_m]Seb[/name_m], Sebby are all adorable! Name of my favourite character from the tv show ‘[name_u]Reign[/name_u]’ as he’s played by [name_u]Torrance[/name_u] Coombs who is dreamy! Can also imagine it at any age as there are so many variations to grow into.
[name_m]Oliver[/name_m] - Classic name for a reason, safe choice. Automatic nick name of [name_u]Ollie[/name_u] which is undeniably cute
