Reply To: Discussion on age of three at maximum age at which an uncle can touch a niece

There is however, some dispute as to what age the Chazon Ish was referring to when the proper tznius guidelines should be instituted. Rav Yaakov Kamenetzky opined that until age five, there is no doubt that there is no issue. After that, he maintained that it is not clear-cut and it would depend on each individual girl; he posited that one should therefore be stringent from age five. However, most poskim estimate that the Chazon Ish meant age 6 – 7, depending on the individual girl.
