as one who has a dh who does this to me I agree 100% it is NOT about the eraser or the cell phone it is about undermining the others ability to parent it's about a power trip for the other spouse this at times is a great source of aggravation in my marriage address this with the offending spouse before it spirals out of control and you find yourself resentful and angry it will fester and ruin your relationship!!!
What if the power trip is on the mom's side? What if Dad thinks that mom goes out of her way to discipline the 12 year old and never the 8 year old. No, he shouldn't have disagreed in front of the kids but what if the mom is wrong? My DH will often hand down "punishments" for no real reason other than to think his is being "super Dad". We talk about that frequently, not in front of the kids, but it is hard to watch him make these arbitrary decisions and not say anything. His favorite is not letting DD go to a friend's house. He doesn't understand why she needs to go to a friends house or have her friends over and thinks she does this too much, this coming from a hermit. There is no rhyme or reason to his decisions and DD has figured that out so she will ask me before Dad because she knows I am more reasonable about that then he is.
In the OP's case the whole eraser thing should have been a TOTAL non-issue to begin with and not worthy of a punishment.
I would love to know how the conversations went between sisters before this all happened too.
It's about a husband undermining his wife's authority to parent their children and sabotaging her ability to discipline. The other stuff is trivial.
It doesn't matter that the 8 y.o. could have brought her own. Coulda, shoulda, woulda. She didn't and that's what the mom had to work with. What she got was a 12 y.o. who wanted to draw a line in the sand over an eraser vs. obeying her mother.
It matters not whether the 12 y.o. is old enough to have a phone....She HAS one. That ship has sailed. According to this mom, taking the phone away makes an impact on her DD. Isn't that what she was aiming for?
She asked the child to share and made it clear what would happen if she did not. The child CHOSE to defy her. Therefore, the child CHOSE the consequences. Then Daddy let her off the hook. Bad, bad, bad...
Bad for a marriage, bad for parenting together.
No, that just sounds like a battle of wills and for that family's sake, the mom had best win.
. He used up all of about 12 minutes that year and all the calls were to us to come pick him up when he was done with practices.
