-Is it possible to go to a neighborhood that has an eruv?
-Can you listen online to shiurim on tshuva?
-Can you share “babysitting duty” with another mom in a similar situation so that both moms can take turns going to shul?
Btw, I’ve NEVER heard of the variation stated above..
The kehila waited for the rav to come, but the rav was delayed when hearing a baby cry. The rav tended to the baby’s needs. When finished, the rav continued to shul which is when Kol Nidre began.
