My situation is similar. Initially, the opportunity to care for little ones seemed mutually beneficial. I would give them my time, care and nurturing. They would give me greater purpose, knowing that despite being childless, I had made a difference in their lives. Over time, however, each encounter with neglectful and irresponsible parents made my circumstances seem even more unfair. How could those who care so little about being parents be given such an incredible gift (often many times over) and take it so for granted. Caring for the little ones was a great privilege, but it took a significant emotional toll.
