Some people (especially my parents) love to tell me all the things my DS will do/be interested in because "he's a boy." It's all stereotypical male activites/interests like pretending to swordfight, being interested in trains/cars/construction equipment, playing superheros, being incredibly fearless/rambunctious, etc... DS is almost a year, and I feel like babies are really gender-less for at least the first year. He has not exhibited any of these interests or behaviors yet, but they might start soon? When did your boy starting doing typical "boy" things? And did you introduce them, or did they just pick these things up on their own?
