RD: cleaning needs depend on the size of your home, compounded by the amount of furniture, knick-knacks and belongings one owns. I think you are not aware of how much stuff families with kids have. And it’s not davka extras.
Growing kids constantly need new clothes, games etc. Basically everything needs maintenance, sorting, mending, laundering etc. And kids need a lot of your time and attention — from diapering to homework help. There’s more than enough to keep you busy as a parent without physically cleaning the house. Some women are spoiled, or used to it this way, but it’s not as black and white as you seem to think. You can’t compare your current lifestyle to that of a growing family, hopefully in a comfortably sized home. IY”H by you.
