Q. My family’s minhag is to wash netilas yadayim before Kiddush. I sometimes go to a Kiddush on Shabbos morning and eat mezonos, and then I come home and want to make Kiddush again for my wife before my meal. Should I wash before Kiddush the second time also since there are some shittos that I am also chayav to make Kiddush again for myself? Or maybe that’s only a chumra but we wouldn’t say to wash before Kiddush the second time because I was most likely yotze Kiddush already and this Kiddush is a hefsek between netilas yadayim and hamotzi?
Thank you.

A. Most Poskim maintain that you have already complied with the mitzvah of kidush on the day by eating mezonos before, however Shiltei Hagiborim (Pesachim – Rif :20, quoted and explained in Gevuros Yitzchok p. 17) that the kidush hayom constitutes also the reciting of a brocho on wine before the main seuda, when you eat bread.
Horav Shlomo Miller’s opinion is that since in principle you have already complied with kidush following most Poskim’s view and you are repeating mainly for your wife’s sake, it is best to recite kidush first and then wash netilas yodaim.
