" As the French say, we want to kill the baby with the bath."
That, of course, is a jumbling-up of the English expression ... "throwing the baby out with the bathwater" .... but it looks as if the French have something similar. Maybe they do say that ... but it seems an odd and rather clumsy way to do it ! Why kill it with a great big bath when there's so many other ways of doing it !!
When I get back downstairs, I'll have a look in my various "French idiom books" and see what I can find.
Meanwhile, here's the Aston Villa song "Raisonne"
