They are a fantastic combination and sibset. I like [name_m]Leo[/name_m] [name_m]Thomas[/name_m] and [name_f]Mila[/name_f] [name_f]Olivia[/name_f] [name_f]Jane[/name_f]. [name_f]Olivia[/name_f] and [name_f]Jane[/name_f] are popular middles but this is a lovely mix. I think you mastered the “sweet spot” name method!
