I feel like my house is constantly a fucking mess. My wife and I work 80 hours between us and we have a 2 year old and I feel like it's constantly a mess.
We do what we can and often spend a couple hours on a weekend tidying but it's a losing battle.
A Roomba and a housekeeper once a month to do the big things (dust, bathrooms, floors). Worth every penny.
I think having an isolated area for kids toys or an easy to dump bucket to throw everything in would probably help the chaos that I see in other parents' homes but as a childfree person I'm the last who should give advice on that so feel free to laugh and ignore that idea.
Good luck getting a toddler to only play with things in a designated area. They are a full force of nature. I do have a basket or toy bin in each room to shove stuff in but it always comes right back out.
