seriously?? specific?? do you think that any rebbi, rosh yeshiva etc. will slap his kid in front of the entire shul so everyone can see and let you know?? i know for a fact that my rav is an extremist when it comes to chinuch, he raises his kids with yiras shamayim and obviously with petch when neccesary. i hear from my husband how the rav will yell in shul on his kids or punish them. he suggests parents to potch when neccesary, he is a chasidic rav in a certain kehilla.
i think your comment is not so derech eretz toward rabbanim and talmidei chachamim.
also a parent has a right in disciplining her kids without consulting her rav etc. taking in consideration that its just normal discipline which 99.99 percent of parents do, a potch can be normal discipline if not done cruelly like my mother who would give me gezunte petch as a teenager for the smallest thing. i had no therapy and had to torture myself and fight for my life to grow up normal and self confident as i am. i had a miracle that i am normal.
anyway, just whatever you do to your kids make sure that its really out of love and care and chas veshalom punish with happiness. i always show my kids my face as sad and half crying that i have no choice and potch them, they see how i hate to do it and know its just out of love and i have no choice and give them that potch so they behave. REMEMBER: NEVER EVER GIVE GEZUNTE PETCH EVEN IF YOU SHOW THEM HOW YOU CRY AND HATE TO HIT THEM, I SUFFERED MISSERABLY FROM MY MOTHERS GEZUNTE PETCH
