Sibling rivalry

K

How do you deal with the constant bickering and yelling and hurting and the "fine, well you can't play with me anymore!" The tattletelling. It's all the time. I'm 6 weeks pregnant and can't handle it while feeling so sick. What do you tell your kids? My kids are 11, 7, 4. And it's mostly my middle child the 7 year old that gets angry so easily and is super sensitive, that he's always fighting with his sister's. How do I deal? I just want them to get along 😭. Also, I didn't grow up with siblings, I was an only child so it's all foreign to me
