throw out the baby with the bathwater, to/don't

To discard the good along with the bad. The source of this expression may be a German proverb, Das Kind mit dem Bade ausschütten (Pouring the baby out with the bath), and its vivid image of upending a small tub clearly caught on. It appeared in English in 1853, possibly as a translation from the German by Thomas Carlyle, and was favored by George Bernard Shaw, who used it in several books, including Parents and Children (1914): “We are apt to make the usual blunder of emptying the baby out with the bath.”
