Mid Week Revelation: Gender specific

I've learned that gender specific roles are sometimes mixed in my home. On one aspect, I find my son gently rocking and humming lullaby music to his baby dolls. Then, I see his sister jumping around the house and mimicking the obstacles to American Ninja Warrior -all while yelling at the television with the same excitement and animation as my husband watching football. One child aspires to be a Ninja Warrior one day and I'm guessing the other just wants to be a loving father.
