Q. See question above. I learned from a Chassidish friend that on Shabbos morning, a woman can eat or drink without making kiddish until 10 or 11, or whatever the time that shul would be finished davening. A Yeshivish friend told me it was a Halacha not to eat before Kiddush but drinking is okay. Just wondering if both could be correct.? Interestingly enough, this friend was drinking beer after candle lighting and didn’t make kiddish, which I thought was forbidden, same as before Havdallah.  Can you please clarify.
A. Regarding women drinking water before davening Poskim disagree. Some opine that since they comply with davening by just saying a short Tefila or Bracha, then they would be obliged to recite Kiddush even for just drinking water. That is recommended by some Poskim. (Piskei Teshuvos 289: n. 80).
However, commonly many women wait to hear Kiddush until their husbands come home from shul. Igrois Moshe (4: 101) maintains that since a wife follows her husband, and he only recites Kiddush until arriving after davening from shul, she does the same.
Indeed one is prohibited from drinking anything after candle lighting if the Shekia already started, until making Kiddush or before reciting Havdallah. However, before the Shekia, Horav Aharon pointed that Poskim permit drinking water if needed. (Shemiras Shabbos K’, Piskei Teshuvos 271: 12)
