We've heard of couples opting to adopt only during exceptional circumstances - can't conceive/gay/have resources to bring up biological as well as adopted children. Else, seldom do married couples choose to adopt instead of conceiving their own child.
I've discussed this thought with a few people, and they've thrown words like 'own child', 'our blood' etc. However, can't we look beyond all this? Whenever I come across an unfortunate family-less child, I wonder what could have been had he/she been adopted as a toddler. If only, we stopped thinking about 'our blood' and treated every life as it were!
