I WONDER - Did Roman Children Wear Jewellery?

In ancient Rome, children were given a charm called a bulla shortly after birth. This charm was worn around the neck to protect them from evil spirits and to signify their status as freeborn, indicating they were not born into slavery. Roman society did not consider children fully human until they could walk and talk, and many did not survive to this age due to prevalent diseases and illnesses.

What does it mean for a child to be considered 'free born' in Roman culture?

What factors contributed to many Roman children not reaching the age of walking and talking?
