Don’t teach granny/ your grandmother (how) to suck eggs
“Don’t teach granny how to suck eggs” means you should not advice someone who is more experienced than yourself, respect (somebody’s) experience.
In French: ce n’est pas au vieux singe qu’on apprend à faire des grimaces.
Most likely the meaning of the idiom derives from the fact that before the advent of modern dentistry (and modern dental prostheses) many elderly people (grandparents) had very bad teeth, or no teeth, so, the simplest way for them to eat protein was to poke a pinhole in the shell of a raw egg and suck out the contents; therefore, a grandmother was usually already a practiced expert on sucking eggs and didn’t need anyone to show her how to do it.
Example: my son you still have much to learn in this domain, don’t teach your grandmother how to suck eggs.
