There is no contest between the important people in your life.
If you desired your DC as you desire your DH, you'd be locked up. If you tended to your DH as you did your DC, chances are he's be utterly pissed off with being infantilised. Not to mention all the differences between other important people in your life.
As you can tell, I don't like the whole concept of "rating" in these circumstances.
Yes, you will give your time to those who physically need it to most. But that's just what people do, not a competitive ranking.
And yes, some people aren't terribly interested in children, or are in a hurry, or are bound up with something in their own lives. They may be deliberately or accidentally rude. Your role is to teach your DC that such people exist, and the healthy ways of dealing with any such encounters.
Venting on here might indeed be one of those ways.
But if it's not just a vent - has something specific happened - then what you have posted would be way over the top.
