For me a pattern is set by the first child’s first name but it isn’t determined completely by that name. For example:
[name_f]Holly[/name_f] - can be seen as a nature name or just a normal girls name
[name_f]Amethyst[/name_f] - very unusual object/nature name
If [name_f]Holly[/name_f] is the first name of the first child then I can go in a lot of different directions: nature, traditional, vintage, unisex - it’s pretty open with the next kids names.
If [name_f]Amethyst[/name_f] is the first child’s first name then I have made a commitment. The next names could be nature names, gem names, or unusual names but not conservative-traditional. Can’t do DD1 [name_f]Amethyst[/name_f] and DD2 [name_f]Mary[/name_f].
Second child, opposite gender
But if the second child is the opposite gender of the first child, then I have the opportunity to go in a different direction because gender offers leeway for a new or different pattern. So if the first kid is named [name_f]Amethyst[/name_f] then I could probably get away with [name_m]Thomas[/name_m]…but I’d feel more pressure to choose something like [name_m]Cyrus[/name_m].
Two kids & expecting a third:
Let’s say I chose [name_f]Holly[/name_f] & [name_m]Thomas[/name_m] for my first two. For the third could I choose [name_f]Amethyst[/name_f]? Probably I wouldn’t. But [name_f]Holly[/name_f] is a nature name: so maybe [name_u]Rowan[/name_u] for the third. [name_m]Thomas[/name_m] is a old traditional name so maybe [name_m]Walter[/name_m] for the third. [name_u]Marion[/name_u] feels like a similar era to [name_f]Holly[/name_f] and [name_m]Thomas[/name_m]. At this point I’m aiming for boy & girl names that fit either rule: 1) nature names that aren’t too far out or 2) traditional names from roughly the same era-feeling as [name_f]Holly[/name_f] & [name_m]Thomas[/name_m].
Lets say I chose [name_f]Amethyst[/name_f] & [name_m]Thomas[/name_m] for my first two. Can I choose [name_f]Holly[/name_f] for a second girl? [name_f]Amethyst[/name_f], [name_m]Thomas[/name_m], and [name_f]Holly[/name_f] - suddenly [name_f]Amethyst[/name_f] doesn’t make much sense. So in this case I would use gender-specific rules: 1) look for unusual, gem, or nature name for a second girl - like [name_f]Pearl[/name_f], [name_f]Opal[/name_f]. And 2) an old-traditional name for a boy - [name_m]Walter[/name_m], [name_m]George[/name_m], [name_m]Arthur[/name_m].
Unisex names versus gender-specific names:
If I name a first girl [name_u]Avery[/name_u] or a first boy [name_u]Morgan[/name_u] then I have a particular dilemma. Unisex names are a commitment to, well, unisex names. The reason why is if DD1 is [name_u]Avery[/name_u] and I name DS1 [name_u]James[/name_u], then [name_u]Avery[/name_u] & [name_u]James[/name_u] look like I have two sons, not a daughter and a son. Unisex names usually mean that the next child, regardless of gender, will have to have a unisex name too.
Unisex names often pair rather well with nature names, since nature names are often unisex (at least in English). So if the first kid is named [name_u]Morgan[/name_u], I’d consider another unisex name, like [name_u]Avery[/name_u], or a nature name like [name_u]Sage[/name_u].
