Children acquire gender stereotypes and show preferences for specific kinds of toys between which of the following age groups? 5-9 years 7-9 years 2-3 years 3-5 years

Kids start preferring a specific gender when they are 2-3 or 3-5 years old. I know this because I have a little sister and right now she is 3-4 and she has started wanting barbie dolls. Since she was 2 she like Anna or Elsa doll's.
