Syag > that doesn’t give you a free pass to “pasken like mommy”,
I full reserve my right to enforce my halakhic authority, I just rarely have to.
Halakha is that you believe one kosher witness in isurei, or as one Rav said – if we don’t take women as witnesses, I can’t eat in my home – and this is literally what we are discussing. I am obviously not saying that the lady of the house issues her own psak, but she follows what she learned in her school, and kids bringing humros from school needed to understand that they should follow family minhagim and not whatever a random teacher learned in her seminary. An obvious sign that the kids concerns were not l’shem shamayim was that they proposed humros rather than implementing them in the kitchen. This is no insecurity any more, btw, kids already learned that lesson by now.
