Like the title says is there a category that already exists to indicate if the love interest already has kids especially one that indicates teenage/grown kids because that is a different plot focus than young kids which often focus more on caring for the child.

the only categories I saw for love interests with kids were for gay stories as "Seme with Kid" and "Uke with Kid" which while valid categories are not a general category that can be used on all relationships (female love interests, straight men, and gay guys without seme/uke set roles can come with kids too)

If there isn't an existing category I will probably go with "Love Interest is Single Parent" as a general categorty for love interests with kids and "Love Interest has Teen/Grown Adult Kid/s" for all love interests with older kids leaving out the single parent part to make it shorter. If anyone can think of a better way to word the two categories I am open to suggestions.

Don't expect proper grammar from me. I am not being paid here, so you get internal monologue in written form.

Single parent, single mother & single father are already categories. I think "love interest is a single parent" would be slightly redundant. Maybe "parent of older kid/s" would be better?
