Unfortunately there were some misinterpretation and it started a mini-twitter-war on the correct definition of a 母亲.
I know there are different ways to become a 母亲 (giving birth, adopting, marrying someone with children, etc). I became a 母亲 when my baby was born (that is the perspective I am writing from as it is the only 母亲-experience I have). Being a 母亲, however, is much more than that in my opinion.
I was trying to make the point that all the every day things mentioned in the post makes you a 母亲 and not just giving birth as the Oxford dictionary defines a 母亲.
What do you think makes a 母亲 a 母亲?
