K.S.
I recommend looking at what activities or events you are doing that makes things feel so hectic. Make a list of what happens every week, then make a list of things that come up periodically like extended family, trips, etc. Then review the list to see what things can be eliminated.
Make sure that at least two weeknights there is nothing planned. In our household, I get one night for my activity, my husband gets one night for his activity, and my son gets one night for his. And only plan one thing for each weekend day at the most. I know some people who have extended families putting a lot of pressure on them to come for visits. Limit each side of the family to one visit a month if they are in town and less frequently if it involves a long drive.
If shopping is taking up a lot of time, consider doing one of the delivery services like Simons Delivers. If cooking and meal prep is taking up a lot of time then think about doing one of the meal prep places like Meals in a Bag (formerly Mix It Up Meals), Let's Dish or another. I do that and it saves me a ton of prep and clean up time at home.
