I told my mom to grow up

My mom isn't talking to me at the moment (even though she lives in my apartment). My mom is staying with me because she and my dad are going through a divorce. I'm currently pregnant. Mw and baby daddy aren't together but coparenting. I have two younger siblings, 10 and 8 and my parents are handling this divorce so immature. This divorce is about revenge. They are trying to take the kids from each other and are using the kids to hurt each other. Telling the kids "You're never gonna see mom/dad again" telling each other they're gonna make sure the kids hates them. When my mom got the kids over the weekend she didn't even spend time with them. She went out with her fuck buddy and left my siblings with me her entire visit. My mom came home on the phone yelling at my dad while my siblings were over and told the kids their dad is a piece of shit and she's not letting them go back and they started crying so I told my mom she and dad need to grow the hell up and stop this stupid revenge shit. They're always making the kids cry and they are acting like children! They are kids, not a fucking toy you don't want to share so you can make the other person mad. You guys are grown adults with two young kids. Start acting like adults! She called me an ungrateful bitch(again shes living with ME) and left. I had to wait for dad to pick to kids up and he's not talking to me because he thinks I'm taking mom's side. My parents seriously need to just grow up.
