[name_u]Reid[/name_u] is my favorite individually, but I think [name_m]Harris[/name_m] goes the best with [name_f]Lila[/name_f]. All three names are great though.
[name_f]Lila[/name_f] and [name_m]Harris[/name_m] is really cute! I have a dear cousin called [name_f]Lyla[/name_f] who I often calm Lylie, and Lylie (or Liley, with your [name_f]Lila[/name_f] spelling) and [name_u]Harry[/name_u] would be such cute nicknames for these two!!
[name_u]Pierce[/name_u] I’d love to see it used more.
