Once upon a time, there was a little boy. His name was Firstborn. He was the sun and moon and stars to his parents. There had never been another child to ever rival this one. Beyond unique, he was truly, as his name suggests, a firstborn, in every way a firstborn might be understood. He not only received complete adoration from his mother and father but true admiration as well. They had never seen a child in the world grow up and learn and adapt and change and delight like him before. They had also never navigated the terrible twos, horrible threes, and fierce fours before either. It was a learning curve for everyone.
