I often say that after 3, a couple more to the mix truly doesn't feel much different. Do your kids and your ex wife's quasi-stepkids get along?

Did your SO not enjoy motherhood? What's with the "adamant" to have kid free Sundays?

If anything, thinking about food bills, one Sunday seems a fair compromise. Is your exwife going to be open minded to this discussion?

I'll be perfectly honest. My ex due to work schedule only gets to see the three sons on Sunday. If he came to me with this dilemma I'd wonder a great many things. So it is certainly touching a nerve, as when I was a teen my father made a choice to send me to live with my mother, shortly after he remarried and she became pregnant. The rift still 25/26 years later never repaired itself.
