Your House Moments Before A Call

Hey Brooke,
I posted this question few days ago and haven’t seen a response yet.

I was wondering how do you set your family before each call so that it’s always uninterrupted and super quiet.
I am scheduling webinars and always let my family know in advance as well as few moments before the time and there’s always something and my office door is been opened, kids fight and scream, etc.
