What is the ruling on men and distinguishing sons wearing bracelets of all kinds, and what is the advice to parents regarding their pre-pubescent children wearing them?

It is not permissible for men to wear bracelets of any kind, as this constitutes imitation of women and non-Muslims. The Prophet, peace and blessings be upon him, cursed men who imitate women. The prohibition and sin become more severe if the bracelets are made of gold or silver. Guardians must raise their children with proper Islamic upbringing, for effeminacy and imitation of women and disbelievers are a dereliction of trust and an act of disobedience.
