How do yall clean the house

I Can't seem to get the house to stay clean.

I need some expert cleaning advice. My wife and I have 3 kids our newest is almost a month and a half old. I want to keep the house clean for her but I always get so distracted and ill start one room find something that belongs in another go to put it there and start cleaning that room leaving what I was working on half done. I really want to buckle down and get the house nice and staying nice so we can have more us time and to keep it clean with 3 Littles in the house. The kids are 6 and 4 so they are always always making a mess everywhere they go. Im desperate for any and all advice.
