My dad was one of 13. I am one of 7.
Today four or more is perhaps considered large. When you think about it the financial demand on families is more now.
As a child my parents gave us what they could afford. It is not always the case today.
I have four in full time school.
Pros
They have each other to play with. I only have one daughter and sometimes she feels left out.
Learning to delegate the work load. (must be what they are able to do)
We care for them, they care for us in their own way
As we get older we will not be alone, they will come back to visit with their children
It is a wonderful experince watching them grow from the baby stage to 6 9 12 and 15. So rewarding
With the way things are now I do not think a lot of people will have lots of children. Some may but some will not.
Even though I have four children I also childmind 5. So usually there are children around me.
Cons
You seem to pay more for family rooms
Taxing of seven seater car
When eating out (age 12 counted as an adult sometimes
