I don't think there has yet been a situation where I have had to weigh up competing needs of DH and DDs that are of equal importance.
They are little girls, he is a grown man.
So what they want and need are entirely different from what he (and I) wants and needs.
I find this question quite perplexing, despite its regular appearance.
It just seems so meaningless.
All of the people in our family are equally important. We aren't competing with one another, we are (hopefully) supporting one another.
No way would I lock myself into my bedroom. Apart from the fire risk, if my kids need to come in to my room, then can come in. They barely ever do.
I kiss whomever is closest. It's not a competition, I have plenty of kisses for all of them.
I do try to teach the bigger DDs not to interrupt people when they are talking. Not because grown ups are more important, but because it is not good manners to talk over people.
