After telling this special episode of their lives, the girls felt nostalgic and decided to look through Lily's baby book. There were all kinds of pictures of her. There were a few sonogram pictures of her growing inside her mother. There were a few from shortly after her birth, where the family hired a professional photographer to take pictures of her sleeping on soft blankets. There were those from holidays, like Halloween, Christmas, and Easter. And a few from her first birthday. And everything in between.

"Look," said Leni as the pointed to a picture, "there's her first sand castle!"

Luna pointer to another picture. "And her toy piano. She really beat those plastic ivories."

The girls were having a fun time looking through this visual biography of their youngest sister, but Lincoln was still a little glum. Finally, Lana spoke.

"I still don't get it, Lincoln. How come you hated her at first, and then you suddenly loved her?"

Lincoln sighed. "I don't know. When I saw her, I just...felt something inside of me. When...she looked at me, I felt...I felt that...I had someone who wanted to be with me. I felt...needed."

"Aww, don't feel bad, Lincoln," Luan said. "Think of it this way: Lily needed you as much as you needed her. You were her first friend."

"Yeah," said Lynn. "you took that sleepy little gremlin and helped turn her into a giggling ball of sunshine."

Lori then spoke. "And you're right about one thing: Lily is special. She's literally full of love and life, she helped you learn to be more open and accepting, and the day we all met her, we all came together like never before. You made a promise to always be there for her, and you more than made good on it."

"Thanks for the compliments, guys," Lincoln said in a disinterested tone. He then asked, with a hint of fear, "But does Lily love me now?"

"Well, bro," Luna said with a heavy head, "that's for her to decide."

Suddenly, the front door opened.

"Kids, we're home!"

"Come here and meet the new Lily!"

The girls got off the couch and clamored as they got to the door. Lincoln wasn't in the mood, so he didn't come with them. From what he was hearing, the girls were liking what they saw. After a few moments, Lincoln felt his father's hand on his shoulder.

"Lincoln, don't you want to see Lily?"

"I think the real question is...Does Lily want to see me?"

"Does she?! Lincoln, she's been anxious to see you all day!"

"She...She has?!"

With that revelation, Lincoln shot up from the couch and ran toward the front door, telling his sisters to move out of the way so he can see. What he saw was breathtaking. There before him was a toddler with a puffy little tuft of blonde hair. She was wearing a lavender t-shirt, blue pants, a puffy pink tutu, and a headband with a big white flower on it.

"She's...beautiful..."

The toddler looked up at him, and he was struck stiff over this creature that looked so alien, yet somehow familiar,.

"L...Lily?"

The toddler jumped up and down, making an excited, high-pitched squeal as she did, and ran toward her brother. She jumped on him and pinned him down on the floor, where she hugged him and kissed his face so thoroughly.

And then she spoke.

"I love you, Lincoln!"

Those words. The four words he had longed to hear from her were finally said. His eyes started to well, then started to leak. He sat up, and he put his baby sister in a soft, tight embrace.

"I...love you, too...Lily. I love you so much!"

Lincoln continued to cry. But these tears were now happy tears, because Lincoln was now reunited with his beloved baby sister. And he discovered one of the upsides of her maturity into a big girl: she was now able to make it clear how much she depended on, and how much she loved, her big brother. Their sisters and parents looked down on the sight with smiles, some of them getting teary-eyed themselves. This was a rare day when it seemed that the family was more united than ever before.

The next Sunday, with Poppyseed Avenue on the air, Lincoln watched from the couch as a gaggle of babies crawled and teetered about on the floor in front of him. His parents had decided to hold Lily's next playdate at their house, and Lincoln volunteered to help keep watch over Lily and her baby friends. As he watched her enjoy herself at play, he couldn't help but think about what lied ahead for her.

"You know, this past week has been an exciting one for me. It gave me the chance to get to know Lily all over again. Sure, there are some things we won't be doing anymore, but some things will never change, like our love for each other. But no matter how much she grows, Lily will always be my baby sister. Besides, there'll always be fun, new things for us to do, and fun, new things for me to teach her."

He sniffed a familiar stench.

"AUGH! Starting with potty training!"

"Poo-poo!"
