This is so interesting! I had almost the opposite reaction! I wish i had felt the way you do! My feelings of trepidation when i found out my first baby was a boy were entirely because having experienced being a little girl and then growing up as a woman, i felt confident in my ability to raise a strong, confident woman. Having never experienced being a little boy, or a teenage boy, i have no idea about all of the things they experience in society, the impact of their hormones on their emotions, etc, and so i felt - and still feel somewhat - lacking in the insight i might need to help me in my job of raising a good man. As you say, the patriarchy is alive and kicking, and i worry about my ability to combat its influence on my boy, having never been a member of that club!
I'm doing my best, but i do think that we can't underestimate the power of society/community on our kids. People like the OP exist, pushing their gender stereotypes! And i still worry that as my son gets older he is going to be exposed to more and more of that, and i not only have the disadvantage of being a different generation to him, but i also just didn't experience growing up male in this society so i wasn't exposed to the same gender pressures/stereotypes he will be, so i just don't have the insight i might need to be forward- thinking about all these things.
Anyway, all that said, little boys really are lovely, and they do love their mums. My son has definitely asked me to marry him already!
