The little guy followed the sound and turned, at first showing no response. It wasn't until Mu WuXie stepped forward, drawing closer, and smiled at him, that an immediate array of expressions blossomed on the baby's little face, signaling excitement.
At seven weeks old, most babies are already able to distinguish their parents from strangers. When they see their mom and dad or familiar faces, they immediately smile, flailing their arms and legs in delight and uttering 'oh oh' and 'ah ah' as if they're trying to speak.
Mu WuXie was reassured; he had been worried that after a few days apart, the baby would surely forget him. But the baby still seemed to recognize the familiar scent on him.
After all, he had been with the child for nearly two months, day and night, and it was truly hard to let go all of a sudden.
