• Sex = Biological (like having XX or XY chromosomes)
• Gender = Social (how society thinks you should behave based on whether you're male or female)

Example: A newborn baby might have male biology, but if society starts giving him dolls and dresses, his gender role becomes influenced by those societal expectations.

• Gender Identity: How you see yourself - male, female, or something else entirely!
• Doesn't always match the sex assigned at birth. Think of it like a personal compass – pointing to who you feel you truly are!

Real-World Example: In India, besides male and female, there's an official third gender: transgender.

• Some brainy people think as early as 18 months! 😲
• Most agree that by age 3, our core gender identity is pretty solid.
• It’s like setting jelly. Once it’s set, reshaping it is super tricky!
