Nothing wrong with eating later, in fact we prefer it because fast food is kinda crap and I don’t really like them eating processed foods. But it definitely saves time, not to mention on the cleanup side too.
And no, can’t really multitask during the weekdays because the timing is so tight. I can do dishes as I go but that’s the limit because the kids start screaming at each other that their feet are touching or whatever the drama of the day is…
