I think for some it has to do with the thought of you not being able to get Nana preggers, which I admit is a little disappointing to me as well, given that nana's age has never been revealed, I assume she was in her early 20's when MC's parents where born, MC's parents looked to be in there early 30's when they died(if chart is to be believed) ad what I assume is 10 years for raising MC and she's at least in her early to mid 60's, if it was hinted that she was still able but unlikely to get preggers again(it is unlikely but depending on hormones and health with a dash of good gens and some women can still get pregnant at this age) it would probably shoot her up some peoples lists, it wouldn't be an impossible ask, or Moonbox could just have nana start some experamental drug trial to help the doc which extends life expectancy in the elderly by 20-30 years, and side effects may include increase hormone production restarting menstrual cycles, stimulating milk production, and increased libido. this is just my thoughts though, it's up to Moonbox whether he wants nana to be able to have baby fever or not, I think she stands on her own as a great character, though I do think seeing every woman she knows getting knocked up by her man might make her a bit jelly lol the other reason she might be so low for people is, We haven't seen horny nana yet, currently she just acts like a good grandma/Mom, but I think once her engine starts in this race she's gonna speed to the front of the pack, I mean she was a sexually repressed woman who only got married to an agreeable man she could be friends with and had kids because it was expected, so she never got to explore kinks or her sexuality, I will say though Nana strikes me as the kinda woman that likes to watch and injoy a little petting

, that's just me though
