I see this ALLLL the time. mothers being jealous of their daughters, stepmothers and gfs being jealous of their bf's daughter or the time and attention that he spends with her. my mom did it as I got older, around the time I turned into a teenager so I know it's even worse with women in the father's life that are not blood related.Yeah, Nas said "I don't know how you could be jealous of a little girl."
I totally get it. It was real weird type of competitive that's not normal, certain women just don't have an off switch when it comes to other females in their presence regardless if their a family member, etc. I've seen women that want the bf/husband to abandon the first family (well first set of kids) or are content with causing friction with the daughters just so they have his complete attention. Vindictive. Stories for days.
