Castle and their son pick up Beckett from work.
"Alright, come on, buddy. Bath time." Castle picked the baby up from his high chair, and carried him to the bathroom. He was spending the day with his little man. He ran warm water, and let him splash around while he got cleaned up. Once they were done, he changed him, and held him against his shoulder. He picked up the baby bag, and were off to pick Beckett up from work.
When he got to the 12th, Hudson was already half asleep. He made his way over to Beckett's desk. "Hey."
Kate looked up confused. "Castle what are you doing here?"
"You asked me to pick you up this morning."
Kate rubbed her temples, the exhaustion starting to play with her memory. "Oh yeah, I did." She started rubbing her son's back, causing him to stir and whimper. She took the baby from Castle, and held him up against her. He gripped her shirt and cried, telling her that he was hungry.
They walked down to the car, and Kate placed him in the car seat, giving him a bottle.
When they finally returned home and got up to the loft, he was sound asleep. Beckett carried him to his room. She placed him in his crib gently, draping a blanket over him. She smoothed his hair, kissing the top of his head.
When she walked into her own room, it was dark. Castle was already asleep. She changed quickly, the bed calling her name. She pushed back the covers, shifted over to Castle's side, and wrapped her arms around him, letting sleep steal her away.
