Q. On Tisha Beav morning someone wearing his Taalis Kotton, should he kiss the tzitzis after Boruch Sheomar or Parshas Tzitzis?
A. Horav Shlomo Miller’s Shlit’a opinion is that the established tradition is not to kiss the tzitzis of the Taalis Kotton on Tisha Beav, and not to recite a brocho on them as mentioned in Shulchan Aruch (O.H. 555: 1).
See however, Mishna Berura (2) on dissenting opinions when one did not sleep wearing the Taalis Kotton.
Nitei Gavriel (57: 6) quotes opinions that children who always make a brocho in the morning on them, should do the same.
However, the Rov maintains that even children or those young men who do not wear a regular Taalis yet and usually recite a brocho and kiss those tzitzis when davening, should avoid doing so during the Shacharis of Tisha Beav,
