We are having our 4th boy and naming him has been such a challenge! I like old, vintage baby names.
Siblings: [name_m]Henry[/name_m], [name_m]Leo[/name_m], [name_m]Gust[/name_m]
Here are some names we like: [name_m]Felix[/name_m], [name_m]Iver[/name_m], [name_m]Otis[/name_m], [name_m]Warner[/name_m], [name_m]Frederick[/name_m], [name_u]Basil[/name_u]
Thank you in advance!! xoxo
Congratulations on your 4th boy!

[name_m]Otto[/name_m]
[name_m]Oscar[/name_m]
[name_u]Oliver[/name_u]
I really like [name_m]Iver[/name_m]/Ivor! [name_m]Felix[/name_m] is a lovely youngest boy name too.
Maybe [name_u]Alfie[/name_u]/Alfred? Or [name_m]Otto[/name_m]!
Love your boys’ names! [name_m]Gust[/name_m] is super cool, is it a form of [name_u]August[/name_u]?
I really love [name_m]Felix[/name_m], [name_m]Otis[/name_m], [name_m]Iver[/name_m] and [name_u]Basil[/name_u] for you! I think short and quirky-retro works really well in your set.
Maybe…
