[name_m]Brother[/name_m] would be R0bin.
These are the names we agree on for a boy:
[name_m]Cedric[/name_m]
[name_m]Wesley[/name_m]
[name_m]Fox[/name_m]
We are not big on nn but I could see [name_m]Cedric[/name_m] being shortened to [name_m]Ricky[/name_m].
Wesley.
Fox reminds me of the animal and Cedric reminds me of the sorcerer from Sofia the First (although that’s probably just me 
)
Wesley and Robin just sounds right.
[name_m]Wesley[/name_m]! It has the same classic, friendly, woodsy feel as R0bin. 
[name_m]Wesley[/name_m] gets my vote but [name_m]Cedric[/name_m] is a close runner up! Both are great choices. [name_m]Fox[/name_m] is a little too “animal themed” with big brother’s name for me personally.
[name_m]Wesley[/name_m] [name_m]Fox[/name_m] maybe?
[name_m]Cedric[/name_m] 
so charming!
Firstly love R0b1n 
[name_f]My[/name_f] favourite is [name_m]Cedric[/name_m] I like the vintage charm the overall sibling set provides. Whereas [name_m]Wesley[/name_m] has never really appealed and I think [name_m]Fox[/name_m] with big brother is just too animal.
I like [name_m]Wesley[/name_m] best with [name_m]Robin[/name_m], followed by [name_m]Cedric[/name_m].
[name_f]My[/name_f] first thought was [name_m]Wesley[/name_m] but now that I think of it, I really love R0bin and [name_m]Cedric[/name_m] together! Feels a bit like medieval knights together Any of these are lovely but I think [name_m]Cedric[/name_m] is getting my vote.
Good luck!
[name_m]Wesley[/name_m] & [name_m]Cedric[/name_m] are my favorites! They both sound lovely with R0bin, and share that soft, nature-y feel.
[name_m]Wesley[/name_m]!
I like [name_m]Cedric[/name_m] and [name_m]Robin[/name_m] together
Wesley! It’s one of my faves as well - though I swing between it & Westley.
Cedric makes Robin more dark academia/ medieval if that’s where you’re headed, though I don’t love Robby & Ricky, prefer Robby & Wes). Fox is a little on the nose being another animal. I prefer it as a middle or a nn. Cedric would be my second choice as it is def spunky.
[name_m]Cedric[/name_m]!
[name_m]Cedric[/name_m] and [name_m]Robin[/name_m] would make such a great pair!
[name_m]Robin[/name_m] and [name_m]Wesley[/name_m]!
I like [name_m]Fox[/name_m] the best
I love the suggestion of [name_m]Wesley[/name_m] [name_m]Fox[/name_m]!
wesley!!
[name_m]Cedric[/name_m] gets my vote! [name_m]Robin[/name_m] and [name_m]Cedric[/name_m] sound so cool together! I imagine two adventurous, brave and enthusiastic brothers. [name_m]Cedric[/name_m] is a strong and refined name.
[name_m]Wesley[/name_m] is also a great choice! I love the sutle nature connection between [name_m]Robin[/name_m] and [name_m]Wesley[/name_m].
