Ok so last night me and my husband and our kids were at my in laws. My daughter was throwing a major fit. She was kicking and slapping her daddy. Well my fil doesn't like my daughter being disciplined at all. He thinks that a tap on the butt is beating. Well my husband tapped our daughter on the butt to calm her down and his dad drew his fist back as if he was going to punch my husband. Fortunately my husband had his back turned so he didn't see his dad draw his fist back. His dad says just because my daughter is his granddaughter that she doesn't need to be disciplined. He has spoiled her so bad to the point that she doesn't listen to me or her daddy. She will scream at us when we ask her not to do something and when she wants something sweet like a cake or candy before she eats her food first and if we tell her no she throws a fit and screams at us and my fil says it's ok if she eats something sweet first right after me and her daddy said no. We have told her that if she doesn't stop that she will not spend the night with him anymore but that doesn't help. I don't know what else to do. It's just to the point that nothing at all works.
