Being able to conceive and bear a child is a blessing. And it’s never a sure thing until the baby is born healthy, so it should never be taken for granted. The tzaar of someone who wants kids but cant bear them is overwhelming.
BUT
I must take issue with those who consider it an “affront to Hashem” if a woman does not want to bear children. Simply put, you have no idea why such a feeling is expressed. The individual may have suffered a trauma, or abuse, or neglect as a child or young adult that makes the thought of raising a child into a world where she has suffered so much an abhorrent thought. The individual may simply be terrified at the responsibility.
Pirkei Avos says in the second perek not to judge another until you have been in their place. Hillel Hazokein said it! I can not see how anyone can bring themselves to argue with this. Not only becasue it is the wisdom of Hillel Hazokein, but also because of the obvious logic of it.
So, those of you who feel it is an affront, who are you or any of us to judge that? Have you walked in her shoes? Doesn’t HKBH rule with compassion and understanding?
So what would I say to her? I would say that I pray that HKBH brings her happiness and fulfillment in her life.
