Birthday Lunch -

Emily smiled as she watched Kate walk a few yards in front of her, pushing Henry along and chatting away to the baby who was gurgling happily back at her, suddenly Emily felt an arm interlock with hers as she turned and saw JJ grinning widely as her.

"So do you think that she is having a nice day?"

"It certainly looks like it, she adores Henry."

"Oh I think that the feeling is mutual!"

JJ slowed slightly as she turned and looked up at her friend, all the time she kept Kate and Henry in her sights.

"How are you Em?"

"I'm good thanks, it's great seeing Kate this happy, sometimes it is worth all the stress and tiredness to see this!"

JJ nodded as she patted her friend's hand as they heard Kate suddenly shout out.

"Uncle Aaron! Jack!"

Kate then turned and looked at her mom and JJ, waving at them to join her as they started to make their way over to the grass area where Hotch had set down a large picnic blanket as Jack ran enthusiastically towards them, shouting as he did.

"Kate!"

JJ quickly manoeuvred her way over and took a hold of Henry's stroller as Jack warmly hugged Kate.

"Happy birthday Kate!"

"Thanks Jack."

"Come on Kate, I've got a present for you!"

Emily shook her head as she watched Jack take a hold of Kate's hand as they ran over to Hotch who smiled at the two children as they sat down on the blanket, speaking quietly to the two of them as they sat perfectly still waiting for Emily, Henry and JJ to join them.

"Hello Hotch, I see that Kate has already said hello!"

Emily sat next to her daughter, letting Kate snuggle close to her as Jack positioned himself in front of the two of them.

"Yes well seeing as it is her birthday I can forgive the over-eagerness!"

Hotch grinned widely as his dimples shone through before Jack started to bounce up and down.

"Can I dad? Now? Please?"

Hotch sighed as he raised his eyebrows but a quick nod of his head lead to Jack quickly crawling across the blanket to the large hamper that sat in the middle, rummaging through it before he appeared with a small box and card which he delightfully presented to Kate.

"These are from dad and me, happy birthday."

"Thank you very much Jack and you too Uncle Aaron."

"It was our pleasure Kate, I hope you like it."

Kate nodded at Hotch as she opened the present and revealed the yellow baby-G watch.

"It's lovely, thank you."

"I chose the colour and done my best writing in the card."

Jack spoke quietly and seriously as he watched Kate open the card before she bent over and kissed him on the cheek.

"So you've brought food Hotch?"

"Don't worry Prentiss there is plenty!"

Hotch shook his head and JJ laughed loudly as she sat Henry on the blanket, helping Hotch to pass the food around to everyone as the warm sun shone on their backs.

JJ picked Henry up as he rubbed his eyes and buried his head into her neck.

"Oh well it looks like I'd better be getting someone home!"

JJ smiled as she stood up and put the tired baby into the stroller.

"Thank you for this morning Aunt Jen, I had a great time."

Kate walked over and hugged JJ around her waist as the older woman ruffled Kate's hair.

"I had fun too sweetie and I'll see you later tonight ok?"

"Ok, give Henry a kiss from me when he wakes up."

"Of course I will, now have fun!"

JJ waved goodbye to the rest of the group as she pushed Henry along back towards her car.

"So come on Kate let's go to the playground!"

"Mom?"

"Its fine munchkin, we can see you from here and as soon as we've cleared up we'll be over."

Kate nodded as she and Jack went running over and headed straight to the swings.

Spencer heard the laughter as he spotted the back of Hotch and Emily swinging as high as they could. Wishing he had a camera on him he raised his eyebrows as he walked over and around, standing beside a giggling Kate he cleared his throat loudly.

"So this is what the unit chief gets up to away from the office then!"

Spencer bent down and softly kissed Kate on the top of her head as he watched Hotch and Emily slow down their swings.

"Happy birthday Kate, having a good time?"

Kate nodded as she hugged Spencer and rested her head against his arm.

"Afternoon Spencer, well I'd better be getting Jack back home, I'll see you later Kate."

Kate let go of Spencer and walked over to hug Hotch and Jack goodbye before she wandered back over as Emily stood beside the young doctor.

"So are you ready for Uncle Spence to take you to the Smithsonian?"

"Of course, which part are we going to Uncle Spence?"

"Well seeing that it is your birthday I thought that I'd let you choose Kate!"

"Space!"

Spencer nodded in agreement, after the two of them had completed Kate's science project their common interest in space had continued.

"Ok then I think you two are set for this afternoon, bring her back home at 6pm Spence, not a moment too soon ok?"

Kate looked quizzically at her mom who smiled back at her as Spencer nodded his head at the instruction.

"I've got some things to sort out back home ready for tonight, that is if you are ok going with Spence?"

"Yes of course mom, I guess that you would find it pretty boring anyway!"

Emily leant across and kissed Kate on the cheek.

"Well have fun, I love you munchkin."

"I love you too mom!"

Spencer took a hold of Kate's hand as they walked out of the park and towards the subway station, talking about what they were going to see that afternoon.
