Generations ago it was pretty common for people to share bedrooms, share beds even. Parents would have their kids sleeping two or three to a bed.
These days, could that be considered child abuse? There are residency laws in some areas which require only two people per bedroom. If you have ten kids, you'd need a 6 bedroom house. And at least eleven beds. And eleven sets of bed linens, eleven pillows to fluff and keep clean, eleven mattresses to keep fresh, eleven quilts or comforters...
I cannot even imagine laundry day - simply with the bedding alone. And I have extra large capacity front loader HE machines! Woah.
And then there are the towels. Think about the bathroom situation. We are a family of four and we just barely have enough room to hang all our towels. The boys share a bathroom and so we hung an extra towel rod so that they each have a place to hang their towel after they shower. But can you imagine even 5 kids sharing a bathroom? Ten? Woah.
And if they don't share a bath... or if you have let's say 4 or five bathrooms.... and two or three share a bathroom... still.... somebody has to scrub all those sinks, toilets, floors... think about all the cleaning products you'll hae to buy... and all those chemicals going down the drain... much more than a smaller sized family. Hopefully a family like this would use baking soda or vinegar or other natural cleaners that don't harm our water or wildlife once it goes down the drain.
Where do you put all those toothbrushes?
And with all those people taking showers, and all those dishes to wash, and all that laundry to do - do you ever have enough hot water? Hopefully you'll be able to get one of those hot water heaters where you'll always have hot water no matter what. But then - imagine your heating bill! Woah. Hmmm... better get some solar panels!
