Several factors can impact IQ development in children:
- Genetics
- Nutrition

Not necessarily. Children grow and develop at different rates. An IQ score is only one piece of the puzzle and should not be used to label a child. Encouraging curiosity, reading, and play are more important than chasing numbers.
