Outstanding Yael! Thank you for writing this. It will help raise awareness. I love that your asked what can be done instead of doubling down and getting defensive as *some* parents do.
There is an absolute thing that a man is expected to “sire” as you say and that makes him a father whereas to be a mother you need to be nurturing and hands on. I wrote about the difference between what it means to mother and father a while ago when it struck me that the 2 have totally different meanings, expectations and associations. Anyway - superb piece, off to share it on the CF Twitter account. 😀
