It's the stuff you buy. I was a girlie child who loved all things pink and princessy and when I had a daughter, I just found that stuff extremely cute and got an obscene amount of satisfaction buying her bows and frilly things.
Even now, I love doing my daughters' hair and decorating their heads with some kind of hair band or sparkly clip. my older girl loves it so it's like we share a very frivolous hobby of liking pink and sparkly things. I also like girls names that are reminiscent of fluff, or sparkles, or fairies and would have loved to have named my daughter Celestia or Romantica or Astara or any other name you'd give a mermaid. I loved picking out girls names as if I was naming my Barbie. I'm very girly and I wasn't going to start teaching my girls rugby. They seem to like it but I wasn't going to push it onto them if they didn't.
I just wasn't going to do the fluffy pink things with my son (Although he does like a pink t short or pink football boots). He is absolutely football mad, loves fart jokes and Minecraft and is hilarious. We have loads to talk about and he is every bit as valuable, loved and cherished as my daughters. I just love the pink things and so do they.
As it happens, my daughters are fully rounded human beings with depth, character and interests that go beyond being girly but we all like the razzmatazz of the cutesy stuff for now. Their personalities are based on more than colour.
All of my children know that almost any career is open to them and that education, hard work, commitment and motivation are crucial if they want to follow whatever their dream may be.
I love being a mother full stop, but I enjoy having girls because I like putting my babies in pink baby grows and buying my daughters frilly dresses, but it is frivolous and meaningless And it certainly does not hold sufficient gravitas to deem oneself not having possessed the full capacity of motherhood if you didn't have it! Nice if you have all the pink stuff (if thats what you want) but it doesn't mean anything.
You're a mother when you have a child, male or female. There are so many aspects of motherhood that nobody experiences the full scope of, and if any did; I feel sorry for them! Not everyone breastfeeds, not every has all neurotypical children, not all mothers see their children growing up.
