What causes a child to become shy?

3 reasons please (2 at most)

New and unfamiliar situations can bring out shy feelings — like the first day of school, meeting someone new, or speaking in front of a group for the first time.

People are more likely to feel shy when they're not sure how to act, don't know how others will react, or when attention is on them.

(3) They shy when they go far from there parents.
