Yeah that is similar to my sitch. W and I work schedules such that we've always kindof traded off parenting duties. She's just kinda flexing that little by little, assuming (mind reading I know) that it's imperceptible to the kids. But it's glaringly obvious. And yep, we used to do things all together (although sadly not enough, this status quo has been developing long before BD) and now that's disappeared.
