Hm I don’t think she’s necessarily one of those ppl that’s like “yeah I wanna have kids someday” and only really thinks about that kind of stuff once she’s dating/married. Haku seems to have a pretty nurturing nature. I def see her nursing sick/wounded forest animals whenever she comes across them, or raising orphaned baby animals so raising/taking care of someone would come naturally to her I think. I feel like her and Lee would def get baby fever and talk about having like 5 or 6 but once Metal is born and they see how difficult it is to raise a child they’re both like uhhh maybe 1 is fine lol. Though I can see them having at least one more lol
