That's a pretty good point - come to think of it, I didn't let my kids out unsupervised in the back yard together for more than a few minutes until the youngest was 4, so the oldest (more impulsive, more risk taker) was 6. To that point I was either just inside the door where they were in my line of sight, or was in and out with them like, I was outside at least once every 5 min, or I just hung out with them.
And....don't ask what my house looked like until just last year - we finally are not walking obstacle courses on the floor in every room, my kitchen sink and counters are mostly cleared every day, and I just stain-treated my carpets a few weeks ago to get them back looking better. Had NEVER DONE IT because I knew they'd just keep making messes. I was on my hands and knees for 10 hours spread over a long weekend doing it, but it was better than doing it over and over when they were younger and getting mad over the course of a few years when they were super crazy.
I'd also forgo cleaning soap on the counter to supervise them more. Mine are 6 and 8 now, and despite not having a super tidy house for their first 6 years they have adapted to adding on more responsibilities and cleaning up regularly pretty well. 3 and 4 really is still very young.
Also: super easy meals. Super easy everything. Way lower expectations, like when you have a newborn. I found with my kids they really didn't turn the corner to start getting "easier" until the youngest was 5. And now every year gets less physically and emotionally exhausting.
Hang in there, mama. When something has to give for me (between crazy kids and housework), it's ALWAYS tidy house that goes first. Laundry and dishes to eat (no or minimal cook meals come into play) are the absolute minimum that need to be done regularly; everything else can wait for a while.
