Định Nghĩa và Ý Nghĩa của "[throw] the baby out with the bathwater"

What is the origin of the idiom "throw the baby out with the bathwater" and when to use it?

The idiom "throw the baby out with the bathwater" warns against getting rid of something valuable or important while trying to eliminate something undesirable.
