shlishi- a father is responsible for his kids keeping quiet in shul. so much so that he can disrupt his S”E to shush them.
in response to the OP- i put on a tallis at thirteen-family minhag- and shortly after was in sqvere/ new square for shabbos. i had literally hundreds of little chassidishe kids staring, pointing and saying “A kleine’ tatte”. it wasnt funn but you laugh it off. and kids will be kids. and when adults do it to me-i wave.
