I have three with one on the way. It’s a constant struggle to keep the place livable. Before I had children I was not a neat person and kept things livable by not doing things that made mess and staying out as much as possible. Can’t do that with kids, so what’s the trick?
Get help, if you can. We have a cleaning lady come to our home once per week, for four hours and it makes a big difference. Of course it is not enough and we still have to clean every day, involve kids, bribe or extort them like everyone else, lol. But it helps tremendously.
