Never really thought about it. I have 2 daughters, 1st is 21!... yeah, thats right, 21 - gah I feel old!. The second one is 3. The first was very girly. Never interested in sports etc. Lost of emotional times and lots of crying. Even at 21, she is still the same. But she is also incredibly strong in other ways and as she grew we were able to really connect and have some amazing and deep conversations. Now the second one. The 3 year old with red hair is a storm of power, confidence, control and owning the entire world. She has been totally into any kind of sport since she was 9 months. If we are out to eat and sports is on a TV, she asks about what they are playing and when someone scores a point or goal or whatever, she yells louder than anyone in the joint. I don't know where she got this from, because I don't yell - heck, I'm not even that into sports. But there is my 3 year old yelling "touchdown blue team" louder than the college frat guys at the bar. She is into tools and fixing things and wants to measure and use her drill on everything in the house. She is also into dance and some days wants to wear a princess dress and other days "adventure pants". Even in her dress I usually have to try and get her to stop climbing up the side of the stars, every piece of furniture and anything else that is even remotely climbable. It took her a few months to stop pushing the boys at school down, because she wanted them out of her way so she could do the slide, climb the stairs or ride the bike. She is a strong willed force to be reckoned with and my wife and I just keep supporting her. Most of our friends who have boys are no where near as physical as my daughter. They all seems pretty tame and wimpy by comparison. So my point, is that, just because your kid is a girl, doesn't mean you can't do "boy" stuff with them. Their sex doesn't really determine how you should relate to them, it'll be their personality. Remember its how you treat them. And girls can do everything a boy can do, but they can also do girl stuff too, so really they can do it all. Cause you know, a boy wearing a dress in public will get strange looks. But a girl wearing jeans and boots just gets nods of approval for how you are empowering her. Don't underestimate them. Its your job to teach them what to expect from men and how men will treat them. They will melt and break your heart. So prepare yourself, you have two female guardians to train up as the strongest smartest beings in the galaxy.
