Here are my two cents on the subject, just seems an appropriate place to offer some of my thoughts....as a disclaimer, I feel pretty strongly about this subject and will probably say things that others do not agree with. My opinions only.
People are always shocked when I say that I am not finding out what the baby is, and even more shocked when I say that the reason is not because "I want to be surprised" but because "it really does not matter to me whether it is a boy or a girl" and then they say, "just so long as it is healthy, right!?" to which I reply, "Well, as a special education teacher for infants and toddlers, who sees amazing parents every day, I think I can handle whatever comes our way."
I have a hard time with the huge emphasis on gender in our society and our world. I am intent on raising confident, well-rounded individuals. My daughter's playroom is full of interesting materials that are meant to develop her cognitive, motor, adaptive, communication and social skills. It would be difficult for a stranger to know if the playroom was "for" a girl or a boy, because it is not one or the other. It is a child's playroom, full of fun stuff! I steer away from dresses and those types of things because they impede movement and keep girls from actively exploring their worlds. We do not have anything pink, and it certainly took lots of talks with family members to stop greeting her with "I love your hair" or "'you are so beautiful!" because those phrases are ones girls hear much more often than boys, a focus on appearance. (Of course boys hear that they look cute, but they are more likely to hear how cool their truck shirt is). So we talk about how it is fine to be pretty/beautiful...etc. but it is more important to be kind and caring. Not only does it force a girl feel that how she looks is all that matters, but it makes children treat those who may not be so attractive in a negative way (and also makes women spend their hard-earned money of useless products). I hope that I set a good example for her by not spending my time in front of the mirror putting on make up or painting my nails or even using a purse. I also make sure to do plenty of yard work, and my husband and I share all responsibilities as far as household chores go....he actually carries a lot more of the load than I do.
Giving birth to a girl or a boy needn't define what your child is going to be like or how you raise him or her. There is incredible evidence that gender is socialized, and that there are small differences at birth between the sexes but they get magnified by the environment (good books on this are "Delusions of Gender" by Cornelia Fine and "Pink Brain, Blue Brain" by Lise Eliot-I prefer the former) I think "well-rounded" is the most important thing, with the goal being that your child reach her or his full potential and you, as a parent, did everything you could to make that possible. And "nettlesoup", the pink/princess phase seems to be a normal part of a girl working on figuring out which "group" she belongs to and adopting everything that is predetermined to be part of that group...more on this in the book "Cinderella Ate My Daughter" by Peggy Orenstein. My 3 year old has not gotten there yet, but if you don't already have it, "the Paper Bag Princess" by Robert Munsch is an awesome children's book which portrays a strong, smart, capable princess!
