Some parents from my generation and later are aware that children, if supported and encouraged become and learn to do that of which they are capable. Forcing children into preconceived boxes is a rarely recognized force of child mistreatment.
If girls are draw to industrial arts, carpentry, hard sciences and mathematics, don’t get in their way out of fear that they will not turn out to be as feminine as you expect them to be. I know plenty of females with extraordinary skills in non-traditional fields who were also excellent mothers and happy wives.
Parents should not panic if their sons have non-traditional play preferences or career aspirations. Whether or not they choose the kind of partners you expect of them is not a reason to shoehorn sons into activities and roles in which they feel uncomfortable or disinterested.
Children should be encouraged to develop their natural skills and interests.
