I know 2 introverted siblings under 9. The eldest doesn't have a lot of confidence, doesn't like busy after school clubs etc. The youngest is also showing signs of being more of an observer rather than someone who gets stuck in without thinking first.
Both parents are shy & quite anxious people. Were they always going to have more introverted children? Should they automatically work harder at confidence building when children are young?
Is it a nature vs nurture thing? Interested to hear your thoughts.
