It is completely normal for a 6-month-old to have a calm and observant temperament. There is no such thing as being 'naughty' at this age, and personality traits like being quiet or active are not predictive of future social success or resilience. Every baby is unique, and a calm baby is simply a normal variation of development; trying to label them or compare them to other children is unnecessary and often driven by societal pressure rather than developmental fact.
