Any ideas on how to approach this, from a DB/DR point of view?
Yes, act like a grown-up! I see this as an act of disrepect. I never allowed my children to yell out my name and expect me to go to where ever they were (unless of course, it was an emergency). The same should be practiced by the adults in the home.
Don't respond to her yelling. If she acts mad about it then, calmly tell her that the distance from her to you is the same as you to her and that if she needs to tell you something, she can go to you and say whatever she wanted you to hear. End of discussion.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
