would any of jaune's yanderes get jealous when they notice that jaune prefers spending all of his time with their kids instead of with them?
probably not. and here are reasons why:
Yang: her mother wasnt there and only her dad was, so it nice to have both parents
Ruby: same as yang just that her mom was dead.
Weiss: her father was abusive and cold, she likes that jaune isnt like her father
Blake: she was introverted before and now is better. so she wouldnt mind also considering that jaune is basically the sun to her moon.
Nora: bother parents died, during an attack on her (and ren's) village.
Penny: she would see this as jaune enjoying the life she has provided and the child too.
Pyrrah: she was always forced to be a star for the camera, she wouldnt "mind" if jaune give their child some attention
Neo: (i think that) her parents didnt like her, and since she was mute, she barely had friends.
Cinder: salem was her only "mother" figure..... so take that as you may so having a kind and gentle hand like jaune is kinda nice
Emerald: abandoned and was picked up by salem and was taught by cinder.... so "kindness" would be nice
Salem: she has already lost 4 diaghter before she wont mess up raising this one. (or multiple ones)
basically? all have trauma and would actually like that jaune takes time with his kids.
