Strongly agree "不安全不要戴", "小宝宝理论上有长系带的衣服都要避免,容易出危
险". Though not many people would be allergic to the metal "gold", it's
still better to be careful. (Some people are allergic to other metals though
.)
I think in the old days, 金锁金木鱼 was a symbol of wealth. That's why they
were highly valued. I'd value the safety of my baby more if I were you.
