What are your thoughts on equality amongst children?

I've been helping my boyfriend raise his son and daughter. He allows his daughter to use all of the data on his phone(4/5 hours a day). But his son is only allowed to use it for like two hours a week. His daughter is also never disciplined. She is allowed to yell at him and I on a daily basis. I told him I expect him to teach her to be mannerful and it's not only my job to make sure she has basic manners.His son is 9 years old and his daughter is 3.5 years old. His son can never get near him or me because she's attached 24/7. If I talk to his son, she puts her face between our faces and talks at the top of her lungs. My parents never allowed this behavior. So for me, it's new territory. I'm losing my patience and I'm not sure what to do. I continuously ask him to at least put her in time out or take her tablet away. Do something!Then he tells me I don't know what I'm talking about. That him and his daughter have a deep connection. Out of the blue. When I asked him why he allows her to do whatever she wants and never makes an effort to talk to his son. Just the occasional, "how was school?"I want to make things work. But this behavior of inequality is making me feel unattracted to him. Because what if we have a child and he plays favorites. I don't want my future child to feel bad like his son. I don't even like see him feel bad.Parents, are some of you guilty of this behavior or are you against it as well? My older sister said her husband is this way too with their daughter. They have two daughters and two boys. But her husband only pays attention to one of the daughters. via /r/Parenting https://ift.tt/2PQ3bgE
