Hi Yanaz, your kiddo's development is not typical or common, but it is normal (as opposed to abnormal).

You may have found the following information and links to resources elsewhere on the forum, but just-in-case you have not... and for the benefit of future readers... I am posting this list here in response to your question.

Identification of gifted is not always easy or clear-cut. Especially early on. If you are interested in reading lists of early behavior characteristics and milestones, and comparing them with your own child's development, these links may be helpful:
- Characteristics of intellectually advanced young people
- Parenting Gifted Preschoolers
- NAGC's list borrowed from the book A Parent's Guide to Gifted Children
((The first item on the NAGC list of Common Characteristics of Gifted Individuals is: Unusual alertness, even in infancy)).
- Characteristics and Behaviors of the Gifted
- Characteristics checklist for gifted children
-Tips for Parents: Helping Parents Understand Their Profoundly Gifted Children
- Profiles of the gifted and talented which lists 6 different types, categorized by personality/temperament and achievement
- Bertie Kingore, Ph.D.: High Achieving, Gifted Learner, Creative Thinker? (hat tip to sanne)
- A common trait in gifted children, often listed amongst identifying characteristics, is alternately described as: "advanced moral reasoning", "well developed sense of justice", "moral sensitivity", "advanced ability to think about such abstract ideas as justice and fairness", "empathy", "compassion". Links to lists of gifted characteristics include several articles on the Davidson Database here and here, SENG (Silverman), SENG (Lovecky).
- ages at which gifted children may reach developmental milestones
- thread about Early Milestones - what do they mean?
- SENG video: The Misdiagnosis of Gifted Children
- book: Misdiagnosis and Dual Diagnoses of Gifted Children and Adults

Wishing you all the best with your little one; she may keep you on your toes!
