A/N: Here's a short update. This was prompted to me by a user here. I hope to write up another prompt tonight.
"Hi, Dad! Thanks for coming today." Kate greeted, showing her father into the loft.
"I'm glad you asked me to help. Anything for my granddaughters." Jim wrapped an arm around Kate and placed his free hand on her protruding belly. "How are those two doing by the way?"
"Oh you know, the usual, pressing on my bladder at all hours of the night, kicking up a storm." Kate smiled, knowing that while there were downsides to pregnancy, she loved being able to bring her little girls into the world.
"Grandpa!"
"Atticus!" Jim threw his arms out and called out in as much enthusiasm as the three year old, who was running at him as fast as he could. "How's my favorite grandson?"
"We're painting!" Atticus exclaimed as Jim picked him up.
"Was Daddy showing you how?" Kate asked, running her hand through his sandy brown hair.
Atticus nodded.
"Why don't you show us what you did?" Jim suggested, setting Atticus back on his feet and following him as he ran up the stairs to the twins' bedroom. Kate was right behind them.
"Hey, Jim!" Castle exclaimed when his father-in-law and wife entered the room. "I'm so glad you could be a part of this." He held a paint roller and was rolling yellow paint on the walls. "You can grab a paintbrush and start wherever you want."
"Hello, Martha and Alexis," Jim said as they worked on painting little designs on the completed wall. "Katie, should you be in here with the fumes?" Jim asked.
"Oh we got the latex stuff, so I can be in here and help." Kate smiled.
"Look, Mommy! I'm painting!" Atticus called across the room, as he moved the brush up and down with both hands, which resulted in him getting more paint on himself and the floor than the wall.
"I see that, sweetheart." Kate crossed the room to stand next to her husband and picked up a roller from the paint tray.
Castle looked to Kate and smiled wide enough to reach his eyes. "Isn't this great? Our whole family here together, getting ready for Cosette and Harper. It's perfect and I couldn't be happier."
Kate laid her hand on his shoulder and grinned at him. "It is pretty great, isn't it? I'm so grateful for you giving me this life."
Castle stopped painting and leaned in to kiss her. "I love you."
"I love you, too." Kate said, turning back to her painting.
