When both parents are around for the weekend, what does parenting look like? As far as splitting duties?

When it's the weekend and DH and I are both here we take turns doing things. He will do a diaper and take LO1 potty while I grab the girls a small breakfast and water. He will clean up the kids after a meal and I will clean up the kitchen. It's pretty even overall. There will be a few times where one of us will do more duties over the course of the hour so the other can sit for a few, or just hang out with the girls. I have no complaints about the responsibilities being even. I do have to ask him to help bring up a load of laundry or something but I'm always on top of things like that, where he may not even know there is laundry done.

I suppose this could go for weekdays too, depending on what your families schedule looks like!
