Is There a Difference Between Siplings and Parenting

There is a reason also that parents treat them more similarly, and that is because they are more genetically similar. And so the parent is like him this maybe there's some difference, because the difference is not coming from me. But you have to adopt the parentting to the different children. Different rules for one child and the ini. They're also of different ages. And this is an endless conflict. I just tink that's like a genetic confounding in there every programm that i see. So what would some one do? These people have access to the state or do they know about this?
