My next pearls of cleaning wisdom:
Keep the floors clean
People coming to your house aren’t going to run their finger along the dusty shelf, but they will notice if bits of food or dirt are sticking to their socks. With a baby in the house, that means I vacuum downstairs about every other day, but for some people once a week might be enough.
Clean as you go
Spills and such are much easier to clean if you do it right away (or soon after) than left for a long time. Sophie drops a lot of food when she’s eating, so I clear it up after each meal, which is very little effort.
