Due to the 5th degree that Mrs B is getting from her mother-in-law, her sisters, her sisters in laws, ect, she feels compelled to start on a very painful, costly and emotional road of treatments. Why? Because the pressure is on.
Your points are valid, but that’s not what the OP is talking about.
He’s talking about the pain of wanting another child in addition to the 2 he has. As he himself pointed out, he isn’t comparing it to the pain of those who are childless. But his pain is real and understandable.
So in the context of this thread, I would consider your post insensitive.
