I have a daughter and a son, 5 years apart.
In those 5 years I had to sometimes defend all-girls' mom's position (like my mom's - there is a saying"guilty of being a girl's mom"....and yes, there still is something like 'dowry' in my country, even though it's not mandatory, which I consider as a sign of underdeveloped culture) and dealt with thoughtless comments about not having a son. (For example: "Are you not going to try again?" " You will regret not having a son when you are older" "Is your husband okay with not havng somebody to carry the family name?" etc.)
Now that I have a son, and am done conveniently with two kids, I still find myself being furious at such comments that my close friend(mom of two girls only) gets. My old-fashioned MIL now openly throws discriminative comments, adding"as you too have a boy, you understand that your husband means a lot more to me and that you have to financially support our retirement...you will be repaid by your son in the future" which makes me doubly furious! I always snap and talk back. Are you still very keen about such things?
