The other half and I have been together for a long time, kids are happy with our relationship, live with their mum but OH has contact every other weekend.
Various occasions in the last few months where every time OH has disciplined DSD, her mother has been quick to take her side and reassure her that we're in the wrong, so I get the impression that she's not been used to being disciplined for years due to divorced parents.
I've spoken to her gently on several occasions about the way that she speaks to her dad, saying that I think the needs to be more considerate to his feelings (occasions of backchat, rudeness etc, nothing major). One such occasion was last weekend when she'd thrown some language at him and we spoke as a family about how that's not on and we expect a level of respect towards everyone (family or not) at all times.
This weekend she's done it again so I've mentioned it to her 121 and she's thrown her toys out of the pram on it. Her dad has backed me up completely (I wasn't aggressive or dictatorial about it, I just pointed out the incident) now she's telling he dad she doesn't want to see him this week and is witholding contact.
We're going to ride this one out as we feel that if we react to it then we're not showing her that we're serious. I should add again that this wasn't a bollocking by any stretch of the imagination, but I just feel that she's getting to the point where she's so used to getting her own way that she is trying to manipulate this situation to her advantage.
Does anyone else have experience of both parents falling into a gap on discipline and teenagers running rings around them? if so what did you do about it?
