Set aside some time on Saturday or Sunday and have everyone cook together. Make 2 or 3 of every meal, and freeze the extras. Make several small lasagnas, for example, or make up a pile of chicken and freeze the extra cooked ones. We put a lot of pureed vegies in the lasagna sauce too - butternut squash, spinach, mushrooms, etc. The "experts" are all saying that this preparation time is key family time and just as important as eating together. And the kids tend to eat healthier food if they help prepare it.
My mother always made a week's worth of sandwiches for my brother and me - 10 sandwiches didn't take much longer than 2. Just lay out 10 slides of bread, put on PB&J or turkey/cheese, then top with the other 10 slices, and freeze in sandwich bags. Put all 10 sandwich bags in one freezer bag so you can find them. Then pull out a frozen sandwich every morning- it will thaw by lunchtime.
We also buy the precooked frozen turkey meatballs. While the water reaches boiling for the pasta, we put the right number of mealballs and some sauce in the microwave, and they are done when the pasta is done. We put frozen mixed vegetables in a steamer and start that when the pasta goes in - it all winds up done at the same time. Easy easy, and a full meal.
Get the kids to help, depending on their ages - they can sort laundry, put it away, and bring it to the laundry room. They can set the table and sort the recycling. They can take the shoes from the doorway and get them to a closet (in pairs even!). Have a basket or shelf or hook near the door so each person has a place for gloves, scarves, etc. At least when they are looking for something, they know it's in their own basket. Saves time and aggravation.
Get a microfiber duster that will do a couple of rooms and then just need to go in the wash. It's faster and more effective than cloths and sprays. And everyone is supposed to spend 2 minutes brushing their teeth. To pass the time, I take a used washcloth and wipe down the counter and even get the spit marks off the mirror with my free hand! It beats sitting there for 2 minutes and getting upset at the mess!
And don't obsess too much about everything being in its place. A little dirt never hurt anyone!
