At three years of age, Lily Holmes was not stupid. She knew something was wrong with Mummy. For several days now, she had spent way too much time in the bathroom, hunched over the toilet. Lily also noticed that she had been very tired lately and did not have as much energy to play princess with her anymore.

Lily was not surprised when her parents sat her down at the kitchen table, sharing a glance with each other before Molly took the seat next to her. Sherlock knelt down so that he was at eye level with his daughter.

Lily looked up at her father, teeth chewing nervously on her lower lip. She was a big girl now! She would be strong and brave for her mother's sake. "Daddy, what's wrong with Mummy?" She glanced quickly at Molly, hoping she wouldn't see the lone tear sliding down her cheek.

Sherlock brushed the tear drop away before embracing the crying girl. She hugged him back tightly, her tiny hands gripping fiercely to his shirt. He pulled back after a few minutes. After deciding that Lily had calmed down enough, he took a deep breath.

"Lily, nothing is wrong. In fact, we have some exciting news!"

Molly stood up at that, clutching her husband for balance. He rose to meet her and wrapped an arm around her shoulder. His free hand covered Molly's on her stomach. Sherlock turned to his wife, urging her to speak. She rolled her eyes at him and smiled down at Lily. "You know Daddy and I love you very much, right?" Lily nodded, still sniffling occasionally. "Well, we are going to be adding on to our family. How do you feel about being an older sister, Lily?"

Lily jumped off her chair, before slowly ambling over to where her parents were standing. She remembered how round Mrs. Watson's tummy had been before she had baby William. Lily scrutinized Molly's stomach intensely for a moment, poking it several times with her index finger. "You mean there is a whole baby in there?!" she asked in disbelief.

Sherlock and Molly laughed quietly before Molly replied. "Babies start out very small, and then grow bigger with time. It's a bit like how you grow every day. You were once really tiny, too. Do you understand?"

Lily chewed her lip thoughtfully for another moment. "I think so."

"Good. But instead of one sibling, you will be getting two! What do you think about that?" Lily's mouth dropped in surprise before she shyly touched Molly's stomach once more.

"Can I talk to them?" she questioned timidly, looking to her parents for permission.

"I think they would like that very much, Lily. Why don't you introduce yourself to them? It will be part of your responsibility to help watch over them."

"Okay." She pressed her face into the soft flesh of Molly's still-flat stomach. "Hello, little babies. My name is Lily, and I'm going to take really good care of you! You are really lucky because Mummy and Daddy are the best parents in the whole wide world!"

Sherlock and Molly grinned happily at each other over their daughter's head as she continued to ramble on about how much she would love them and any other random thoughts she wanted them to know.
