I had a teenager tell me the other day that “my parent tells me all year long that they will do it for me on my birthday, but every year when my birthday comes around, they don’t do it”. I have a small group of about 30 women and MANY people in that group say their kids experience that with their ex-spouse as well. The ex-spouse promises things (a cell phone, vacation, movies, etc.) but then doesn’t do them. I think one of the biggest problems with that is that the kids start to see their parent as a liar. The parent loses all credibility and the child no longer believes anything you say. There really is no reason to try to win over a child with empty promises. They may be appeased temporarily, but I promise you that they do not forget. They may not bring it up in order to avoid confrontation, but they do not forget.
