When ex is undermining your parenting rules
My kids told me that mom lets them stay up until 11pm on school nights at her place. I have a 9pm bedtime at mine and it's killing me because they're exhausted when they come back. I brought it up and she said I'm being controlling. How do you guys handle when the other parent has completely different rules? Do you just accept that they live by different standards or does this bother anyone else?
Document when they're tired at your place and how it affects their day. If you ever need to go back to court about custody modifications, that stuff matters. Don't let it slide.
