When an orphaned baby boy had fallen into the 12th's collective lap, Castle took that as a sign that he should take a refresher course in child rearing... and if Beckett got swept up in the fun, well then, it would be a worthwhile adventure in babysitting.

-I am the baby Whisperer - Castle thought as he handed baby Cosmo to Beckett

"Uncle Rick's pretty funny, huh? I think you're pretty funny too" whispered Beckett

- Not a baby person? She kept up with me, the RHD. She'll see that she has it in her - Castle tossed the diaper in the trash can

"Ugh!"

- Don't miss the smell of -

turning to make his way back to the lounge room, Rick stopped in his tracks

- those. WOW! If only she knew how beautiful she looks right now -

Beckett was cradling baby Cosmo, like a pro and beaming with pride

"What?!" Castle knew what was up but he waited to see if she could admit it yet

- She's enjoying taking care of him. She felt it, the feeling you have when you bond with someone who depends on you, someone who's full of innocence and wonder. Whose life is why you get up in the morning. And she likes that feeling -

"Nothin'" Beckett said, side stepping a potentially dicey topic.

She felt that feeling, she felt it so strongly that it scared her a little bit. She didn't want to lose this child she'd come to enjoy over the past 24 hours and she didn't want to imagine what it would be like if she lost hers and Rick's babies - Mine and Rick's -

"Alright. Now all we have to do is get him to sleep" Castle sighed wearily

Beckett looked at Castle

- It'll be different when it's our child, right? -
