That depends on what a boy or a girl wants to do. In our world, there are a lot of people who have different personality. It means that childcare methods are also different depending on whom they bring up. There is no fixed methods and circumstances to bring up their kid. Only one question can be existed that what he/she wants to do now. It's true that boys and girls have different innate tendency like boys are reasonable and girls are emotional because of sexual difference. However, It doesn't mean that they grow up differently. This can be changed when children ask themselves what they want to do and find it. Parents don't have a right to choose what their child do in the future or what he/she learn. They just support their child with the question 'what do you want to do now'. This also good for their kid. At first, this would not work as child have low intelligence. However, If that period ends, I'm sure that this work in his/her whole life.
