Question:
I light one extra Shabbat candle for each of my children. Is it acceptable to also light an additional Shabbat candle for grandchildren?
Answer:
Hello,
I don’t see anything halachically wrong with doing this, it is not the accepted things to do. IY”H you will have tens of grandchildren, and it might get quite difficult, and challenging to light tens of candles each week. After lighting your candles, you should however daven for each of your children and grandchildren, that they should all grow up to be yirei shomayim and talmidei chachamim.
Best wishes
