Many years ago I heard a story from an older woman when the subject of child behavior came up.
There was this old lady who had had 7 children and had raised them in a house filled with lovely antiques. After they grew up a visitor complimented her on keeping her valuable antiques so lovely in spite of all those children.
The old lady merely laughed. "My dear," she said, "Keeping the house nice was easy, because in my family, most of the polish was on the children!"
