Charlie, a curious 6-year-old with wide eyes and a mischievous smile, sat cross-legged on the soft carpet, surrounded by his toys. Today was special. His parents had told him he would meet someone new, someone who would change his life forever. "When will she be here?" he asked, his voice filled with both excitement and a hint of impatience.

Mom stood up from the couch, her eyes sparkling with joy. "She's here, Charlie," she announced, heading towards the door with Dad following close behind. As the door opened, a woman holding a small bundle stepped inside. Her smile was warm, and her eyes were kind. The woman gently handed the bundle to Mom, revealing a tiny baby wrapped in a soft pink blanket.

Charlie approached cautiously, his eyes wide with wonder. "Is this my new sister?" he whispered, peering into the blanket. Mom nodded, her voice gentle. "Yes, meet Lily. She's going to be your little sister." Charlie reached out a hand, his fingers brushing against the baby's tiny fist. "Hello, Lily," he said with a giggle as the baby's fingers wrapped around his.

Dad joined them, sitting beside Charlie on the floor. "You know, being a big brother is a big responsibility," he said with a smile. Charlie nodded seriously, looking at Lily with newfound determination. "I promise to take care of you, Lily," he declared, his heart swelling with pride.

Mom cradled Lily in her arms, while Dad read a storybook aloud. Charlie nestled between them, his head resting on Mom's shoulder. "I think Lily is going to like stories," Charlie said, glancing at the baby who gazed at him with wide, curious eyes.

Charlie watched as Lily fell asleep, her tiny chest rising and falling with each breath. He felt a sense of contentment and excitement for the days to come. "Goodnight, Lily. Welcome home," he whispered, knowing that this was the start of a beautiful new chapter in his life.
