Who is waiting while food cooks? When I cook I am attending to the food the entire time. Perhaps if you are a heavy oven user you get time to do other things, but otherwise, no.
And laundry lol. To barely keep up with the laundry, I have to do a load a day and the on the weekend I do several loads. It wasn't like this before I had a kid, but everything grt dirt faster and more often with a child around.
Being a parent who works is _exhausting_. You're always weighing money vs time investment. In many cases it's just easier to buy food you don't have to make or think about then have to do the whole rigamole of planning and buying groceries and then cooking the food yourself. If you're like me and you order a head via an app, you don't even have to wait the few minutes fast food takes. It's right there for you and you carry on your way. I can now spend my mental energy on something else.
