My kids are younger than yours, which has some advantages (no homework, not really any extracurricular activities, longer sleep) and disadvantages (not really able to feed or clothe themselves, need parent help for bathing, still need some assistance on brushing teeth, need to be read to instead of being able to read on their own).
During busy weeks (like when one of us parents is out of town for work or something) we're quick to switch from home cooked meals to takeout or eating out, may hire cleaners, and push off some of the social interactions, but I also recognize that I'm working with a pretty nice buffer in that I'm already hanging out with friends about 10 hours per week.
You're getting the labels mixed up.
As a labeling requirement under U.S. law, anything labeled "American Cheese" must be pasteurized process cheese made from some combination of cheddar, colby, washed curd cheese, or granular cheese, which the law also defines pretty strictly. It must be made from these cheeses, heated and emulsified with an emulsifying salt (usually sodium citrate).
American cheese is allowed to have some optional ingredients and still be labeled American Cheese:
You can add milk, cream, buttermilk, whey, or certain other dairy products up to 49% of the finished product, but then you'd have to call it "Pasteurized American Process Cheese Food" instead of just American Cheese.
American cheese is made from almost entirely cheese ingredients. The individual slices being sold at the store, though, vary by brand on whether they're even trying to be American Cheese (or whether they're some kind of lesser "cheese food" or even lesser "cheese spread" or even lesser "cheese product")
Regular Kraft singles aren't American Cheese. Look at the label. They're "cheese product." Even the Deli Deluxe line has taken a hit in quality in recent years, even if they are labeled Cheese.
Go with other brands that actually put together a decent tasting American Cheese, and check the label to make sure it's made with 100% cheese instead of 51% cheese (or less).
