Saturdays are:
Kids lessons, errands, more laundry, family time, playing, and hanging out, kids' homework, play dates, etc.
No matter what day of the week it is, my kids always wake up in the morning, early. BY 6:30am. They have been this way since they were babies. Me, no matter what day of the week it is, even on weekends, I am up EARLIER than everyone else. Only my Husband, is the one that sleeps in.
Sunday, are whatevers. My Husband usually does something with the kids... so then I get my alone time. He's good about spending time with the kids. Mostly because, his Dad, didn't. So he doesn't want to be like his Dad.
I am a SAHM too, and also work part-time during the week.
But everyday, I do cleaning, laundry, errands, chores, being with the kids, etc. everyday of the week, including weekends. And sometimes, I just do my own "I am not doing anything this weekend..." type things. Why? Because I take a day off, for myself. And I tell the whole family.
Oh and on Fridays, that is my own tradition of "I don't cook dinner..." so on Fridays, we get take out or my Hubby will do dinner.
I get so burnt out from cooking every darn day/night. So on Fridays, that is my own day off from cooking dinner.
