I feel like this often, but figure it's because my own kids are very young too, so there is not real down time. I try to cut myself slack where I can. Everything doesn't have to be perfect. Maybe you could give yourself permission to slack off a little on cleaning here and there or find ways to get more done while the kids are eating etc. Organization is key to making things easier. I recently switched everyone into booster seats with trays and the mess is a hundred times less than when they were at a table, I don't have to mop everyday anymore as I just spot clean while they are eating.
