I really like [name_f]Poet[/name_f] nickname “Poe” with [name_m]Ocean[/name_m].
I think they work well together. If he feels [name_f]Poet[/name_f] doesn’t quite fit him when he’s older he can always go by his nickname or [name_m]Wren[/name_m].
If you love the name go for it!
I also think the suggestions of [name_m]Zephyr[/name_m] and [name_m]Cosmo[/name_m] could work perfectly as well.
