Congratulations!
[name_f][/name_f]Firstly love L0la however I do agree I think using [name_m]Louis[/name_m] is going to pigeonhole you into a theme with both names beginning with an L. I prefer siblings to have their own individual initials. Also with the adorably named dogs it really emphasis the shared letters/theme. Similarly would rule out [name_m]Mac[/name_m] as a standalone with the dogs maybe [name_m]Cormac[/name_m] ‘Mac’ could work?
[name_f][/name_f][name_m]Archie[/name_m] + [name_m]Oscar[/name_m] are very dependable boyish choices that feel very [name_f]British[/name_f] playground especially paired with L0la. From the two options my favourite is [name_m]Oscar[/name_m] I just prefer the overall sound along with the shared O sound.
