Reid yawned while standing at the airport. Beside him, Sandy chuckled. "You know, I could have picked Henry up on my own so you could have stayed home." She felt a little pity for the new dad, learning the ropes of sleep deprivation with a week old newborn. Now they were about to add the hyper four-nearly-five year old into the mix.

Reid yawned again and smiled at his mother-in-law. "I know, but Henry is used to us being here to pick him up or flying down to get him. Since JJ has to stay home with Ella, I had to come with you. Besides, I miss my little guy," he answered. They were trying to avoid deviating much from their routine if they could help it. Sandy shook her head; she loved this man more and more. He really treated Henry as his own, loved him just as much as his new daughter, and it warmed her heart.

"Spence! Grandma!"

Reid grinned and bent down to catch the blond tornado. "Hey Henry!" He pulled him into a big hug, a hand rubbing down the back of his head as the boy wrapped his arms around Reid's neck. "I've missed you buddy."

"Missed you too," Henry answered and then pulled back some to look at his stepdad's face. "Where's mommy and Ella?"

Reid smiled. "Well, Ella is still a little too young to come out to a place like the airport so she's at our new home with mommy. After we get your bag, we can go see them and check out your new room, won't that be fun?"

"Yeah!" Sandy reached over and touched the top of the boy's head. "Hi Grandma!" He reached for her and Reid handed him over.

Reid turned to Will. "Thanks for flying back with him. Next time, either JJ or I will travel with him to New Orleans." The southern couple had been doing more of the travel with the boy as of late.

Will waved, dismissing the comment. "It's fine, Spencer. I certainly wouldn't have expected you to come get him with the little one at home now." Will stuck out his hand. "Let me congratulate you properly."

Reid smiled and shook his hand. "Tha—" Another yawn cut off his reply. "Thanks. Sorry."

Will chuckled. "Oh, I remember those days. At least your job somewhat prepped you for a lack of sleep."

Reid shook his head. "Nothing can prepare for you this, but I wouldn't trade it for the world. Although I really wish I hadn't given up coffee." They did get sleep deprived at work, but they were usually running off of adrenaline to catch the unsub. The cry of an infant every few hours or so, just as they could often reach REM sleep was all together different.

Will winced and Sandy chuckled, over hearing that part. "Ouch." Will smiled as he looked at his son talking with his grandma. The group made their way to the luggage area. Will was visiting a few of his old work buddies for a couple days. They had thought it would be best if he were around for a bit, just in case Henry had a rough time with the changes.

JJ heard the voices downstairs, breaking her out of her slumber. She stretched and sat up, peering into the bassinet beside the bed. Ella was still out like a light. JJ smiled and turned on the baby monitor, grabbing her half as she quietly snuck out of the room.

"Wow, look at all the room for books!"

JJ chuckled. Henry was taking after his stepdad, that was for sure. It shouldn't surprise her that the library excited the boy. She came around the corner into the room as the rest were smiling at Henry looking around the room. Reid had somehow found time to unpack all the books. He had left several of lower shelves for Henry's (and soon-to-be Ella's) collection, including his old encyclopedia set. Will spotted her first and made his way to her.

"How you doing, JJ?" he whispered, pulling her into a brief hug.

JJ smiled. "Good. Tired, but good. At least I was mentally prepared for this, unlike Spence."

Will smiled and nodded. "Yeah, I noticed. I was glad Sandy was the one driving us back here. Not sure he should be handling heavy machinery right now."

JJ lightly smacked his arm. "Hush." She looked over at Spence with Henry. "Although maybe I should warn Hotch before he goes back about taking his firearm." The pair chuckled softly.

Henry heard her voice and turned to see her. "Mommy!"

As he ran over to her, JJ smiled and gingerly bent down, still recovering but better than when she first got home. Nothing was going to stop her from hugging her main man. "Henry, I've missed you so much," she greeted as she hugged him tight.

Henry kissed her on the cheek. "I love you mommy."

JJ felt tears forming in her eyes at those sweet words. "I love you too, baby."

The boy pulled back and shook his head. "Ella is baby, not me. I am a big boy."

JJ smiled and nodded. "You're right. You are my big boy. Does the big boy want to see his room?" Henry nodded. "Now before we go upstairs, I need to you try to use your inside voice okay? Ella is sleeping right now and we don't want to wake her until she's ready. But when she's awake you can meet her, okay?"

"Okay," Henry replied in a quiet voice.

"Let's go, Henry," Reid offered his hand to the boy who ran over to him and took it. The group made their way to the staircase and quietly climbed up. Reid stopped in front of a door with a sparkly blue and green sign hanging from it. He picked up the boy so he was the same height as the sign. "Can you tell me what that says?"

He studied it for a moment. "Henry's room." He turned to look at Reid. "This is my room?"

Reid nodded and set him down. "It sure is, bud. Your Aunt Penny made that especially for you." He opened the door and Henry's eyes grew wide.

"Wow," he whispered, somehow remembering what his mom said moments earlier. He ran in and looked around. He recognized his bed, dresser, his play table for drawing, and his toy box. It was just laid out a little different. And his favorite cars were on the wall. He spotted Steggy on his bed and grabbed him, hugging him tight. "My room?"

JJ came in and sat down on his bed. "Your room. Do you like it?" Henry leaned into his mom and nodded. They could all see he was starting to get anxious, the grasp on Steggy an obvious tell, as the changes of the new place starting to pile on. She kissed the top of his head and shot a glance at the others. She was worried; he hadn't even met Ella yet. She was now even more grateful that Reid had read those parenting books about this subject. They had been sure to keep his same bedding and set up the room they best they could to have it feel similar to him in some ways and make the transition hopefully easier. Sandy was going to take him around the neighborhood tomorrow so he could get used to his surroundings. Reid had gotten permission from his principal and teacher to meet with her at the school the next day so he would know her face when he got to school.

"Henry, do you remember this?" Reid held up his red car from Garcia for his birthday.

"Yeah!" Henry replied and ran over to the toy box area and started to play with his favorite car. Will sat down with him and started to play as well. A cry came through the monitor.

Reid headed to the door. "I'll get her, JJ. If she's hungry I'll come get you." JJ nodded and mouthed 'thank you' as he walked out. He headed into their bedroom and soon had Ella in his arms. "Hey sweetie, what's the matter?" Ella seemed to settle after a few minutes of rocking in his arms and after hearing his voice. He soon deduced that she was wet and changed her diaper. He had quickly become grateful that girls were easier to change than boys, recalling some interesting times with infant Henry during his early godfather duties with Garcia. When he picked her up off the changing table, she offered him a faint smile. He knew it was just a reflex, but he'd take it. She also starred up at him. He swaddled her again in her - previously JJ's - blanket and then held her close, kissing the top of her head before heading down the hall.

He was happy to hear some of Henry's chatter had returned while he was gone. JJ spotted him and nodded with a smile. "Hey, Henry, do you want to meet Ella? She's awake now."

The boy looked up at him and nodded. "Yeah!" Reid walked into the room and sat down on the bed. Henry walked over to him.

"Now remember what we talked about," Will started. He had done his part to try to prep his son. "Ella is really small and you need to be very gentle with her, okay? No rough housing like you do with Spencer, Derek or I."

He nodded. "Yes, daddy." He was soon in front of Reid looking down at her. Reid turned her a little so Ella could see him as well.

"Ella, this is your big brother, Henry. He's going to help you to do so many things when you get a little bigger," Reid introduced for Henry's benefit.

"Hi Ella," he greeted. Then he looked up at JJ. "Can I hug her?"

JJ smiled. "Well, you can't quite hug her like you do us, but you can hold her like Spence is. But, since she's so tiny, he's going to help you do it okay?" Henry nodded and JJ patted the bed so he climbed up. Reid shifted Ella to his other arm so he could pull Henry into his lap.

"Ella is still figuring everything out Henry, so she can't hold her head up like you can. So whenever you hold her, we have to be sure to have a hand or arm supporting her head, okay? Like this," Reid pointed out how he was holding her. The boy nodded, absorbing the information. "She also feels better if she's snuggled tight in her blanket so we try to keep her wrapped up like now." Reid, with JJ's assistance, just shifted the baby into the boy's arms, Reid keeping his under Henry's where her head was for additional support, just in case.

Ella blinked and looked up at the new face and cooed slightly. Henry beamed. "She said hi!"

JJ swallowed the lump in her throat. "Yeah, she did, bud. She loves you."

Henry continued to stare at his sister. "I love her too."

Reid smiled and kissed the top of Henry's head as JJ scooted over, wanting to be closer to her family. None of them noticed Will's smile or Sandy taking a few photos of them with her phone.

"You excited, Henry?" Reid asked as he helped the boy slip on his backpack. Sandy smiled at the scene as she held Ella. JJ smiled as well but she was also getting teary eyed.

"Yep!" Henry replied, nodding for added measure. He liked Miss Tanner from his interaction with her the week before and he loved all the books he saw in the classroom. He had also read the book from his grandpa, although he didn't know that's where it came from yet.

"Okay, let's get a photo of you to celebrate this big day," JJ stated, blinking away her tears. The group went outside and JJ took a photo of Henry standing on the steps.

Reid gently took her phone from her, "Go stand with him, Jen." She smiled at him and sat down on a step, Henry standing between her legs as she wrapped an arm around him, holding him tight for one more minute. Reid smiled as he snapped a few more photos for her. "Okay, little man, we need to go so you're not late." Sandy kissed Henry on the head before the boy and his parents climbed into their car; she was staying home for with Ella for the short trip.

They arrived at the school about fifteen minutes later. Reid took Henry's hand and led him to the classroom. JJ followed behind, getting a photo. Then she took some video of Henry approaching the classroom to send to Will and Garcia. Henry stopped at the door and Reid bent down to his level.

"You behave for Miss Tanner, Henry. And have fun learning," Reid stated.

"Be nice to the other kids and you'll make some friends," JJ added, also bending down. She pulled Henry in for one more quick hug. "Love you my baby star."

Henry pulled back. "I not a baby anymore, Mommy. That is Ella."

JJ sniffed, starting to lose it, remembering this conversation from last week. Her son was growing up too fast for her. Reid smiled and rubbed her back. "We know, bud, we know. Love you Henry. We'll be here when you're done with school today, okay?" Henry nodded. "Now, go say hi to Miss Tanner."

Henry nodded. "Okay Spence. Bye!" He waved and ran into the classroom. JJ was starting to break and Reid pulled her up into a hug as he watched the boy settle into the classroom. Miss Tanner caught his eye and smiled; he nodded back.

They started to walk away when Reid felt something on his legs. It was Henry. "Henry?" He picked him up. "What's wrong?"

The boy shook his head. "Forgot to say 'Love you!'" The boy squeezed Reid's neck tight for a second, getting a tight hug back. When they pulled back, Henry reached over for JJ, hugging her and kissing her on the cheek. "Love you mommy!" Reid still held him some since he was a little heavy for JJ to carry right now.

JJ felt her heart clench with such mixed emotions. "Love you too my big guy." Reid set him down again. "Go have some fun, bud." Henry smiled and nodded, waving as he ran off again. JJ snuck her head around the door again, getting some more video of him in the classroom for Will before the couple finally left the school.

As they climbed into the car, JJ sighed. "Is it 3:30 yet?"

A/N: If you don't have me on author alerts, you'll want to check out my companion story to this one - "You are My Sunshine" - which will focus on Reid and Ella. Didn't want this story to just dissolve into the cuteness that is Reid as a father when we've got other story arcs that need to be covered so hopefully that will help fill everyone's desire to see more of those moments.
