At what age do infants and young children usually start being taught to use a small spoon to feed themselves?

Patient's question:

Patient Age: One and a half years old
Detailed Condition and Purpose of Consultation: At what age are infants and young children generally recommended to start teaching them to use small spoons to feed themselves?

Doctor's answer:

It is recommended that children start using small spoons to feed themselves at around one year old, because at that age, children have strong imitation abilities. Additionally, during the initial learning period, children may spill food all over the table or the floor. At this time, parents should not scold or punish them, but instead encourage them, so that the child can find it interesting and learn.
