The first and least affected is the property loss, which is acceptable.
Secondly, it affects children's health, because jewelry is very easy to accept dirt and bacteria, especially some jewelry accessories woven with ropes, which are very easy to breed bacteria and have a potential impact on baby's health.
The third reason is also the most likely and serious, which will affect the baby's life safety. Some common jewelry worn by children, such as safety locks, especially those with small bells on them, baby bracelets, bracelets with small bells, or some decorations, or some children bring some anklets with some decorations on them, are highly recommended.
Because children like to eat and suck some foreign objects in their mouths, they are likely to bite off or suck off the decorations on them and swallow them directly, which has a great impact on the baby's health and life safety, so my suggestion is that children under five years old should not wear any jewelry, just clean it.
