I might add a certain Rebbe I had years ago who was childless and in his 50s at the time I had him. He was one of the happiest most accepting loving people I ever met. When someone told me he didnt have children I was shocked. Shocked! He totally looked like he had the best life and nothing could possibly be wrong. A real Tzaddik and an example of accepting everything Hashem does and saying Letav Avid.
