Unborn babies can start to hear by about 16-17 weeks, and my hubby first felt our little guy at 19 weeks, so that's when this takes place.

Feel free to look up Bryn Terfel's version on the traditional Welsh lullaby "Suo Gan" if you want to hear the song. It's really quite beautiful. I grabbed this particular translation from the Celtic Arts Center Website.

"Hey! What are you up to in there? So crazy this morning!"

Killian heard her voice echoing from the kitchen as he approached, his black cotton pajama pants slung low on his hips as he pulled a blue T-shirt over his head.

"Um, who are you talking to, lass?" he asked, coming up behind Emma to kiss his way up her shoulder. Henry was with Neal this morning, and wouldn't be stopping by for at least another half hour.

"Oh," she blushed a bit, feeling silly that he'd caught her. "The bean. It can hear now. Not that they have any idea what I'm saying. I don't know. I read they they get to know your voice if you talk to them." She lifted her tank top and put her hand on her belly, and he placed his next to it, trying to feel the movement. "Still can't feel it, huh?"

She felt him slouch slightly in disappointment, resting his chin against her neck, his ever-preset scruff tickling her skin. "But you can?"

"Yeah, it feels weird. He or she was going nuts a few minutes ago, but usually its just a strange fluttery feeling. Like butterflies." She laughed. "Or a parasite."

"Oi, that's my child you're talking about!" He responded in mock offense, splaying his fingers a bit wider in hopes of getting lucky. She'd been really feeling the movement for the last week or two, but apparently their little one was still too small for him to feel. "Hmm. Still being as stubborn as its mother, I see." She elbowed him playfully, only prompting him to wrap his other arm around her and pull her closer. "Maybe tomorrow." He tried not to let his disappointment show. It wasn't her fault.

She shooed him out of the kitchen, a glass of OJ in hand, assuring him that she could handle making her eggs and toast before they left to walk Henry to school before she went to work. He wished she'd quit that sheriff job, worried that the physical activity and stress would take its toll, but they'd been over it a dozen times and each time she'd assured him that she felt fine, and it got her out of the house- something she reminded him would be a challenge once the baby actually came. Luckily, David was on his side and had practically demanded she limit herself to easy jobs and desk work. For all their differences, he and the prince completely agreed on this particular issue.

That night, as she drifted off to sleep, she swore she heard- was that music? Rousing herself, she noticed Killian was lying curled by her side, head by her hip and hand on her belly, quietly singing. Not wanting to ruin the moment, despite the fact that she could literally feel her heart melting, she tried to listen but couldn't make out the words. She ran her fingers through his hair, toying with the soft, dark strands.

"That's really pretty. What is it?" She whispered.

"It's a lullaby. I remember hearing it when I was young. You said the bean could hear now and, well, I thought maybe they would like it."

"I didn't know you could sing. I mean, sing well. Or in another language."

"Love, you'll find I'm full of surprises," he teased, nuzzling and nipping at her hip bone. "It's an old song. I can try to translate the rest of it." He paused a moment, then resumed singing the next verse in English.

"Sleep in peace tonight, sleep,
Gently sleep, my beautiful;
Why do you now smile,
Smile so gently in your sleep?
Is it that the angels on high
smile upon you as you happily smile?
While you return the smile, still sleeping, sleeping in peace upon my breast."

He paused a moment, then continued after placing a kiss to her belly.

"Fear you not, 'tis but a leaf
Beating, beating at the door;
Fear you not a lone wave's
Murmur, murmuring on the seashore;
Sleep, my child, for there is nothing
Here to frighten you.
Smile in peace here on my bosom
At the white angels yonder."

"That was beautiful. And I'm pretty sure the bean liked it," she whispered, feeling the little one changing position rather dramatically.

Emma looked down at him, but his blue eyes were focused on her belly, his lower lip drawn between his teeth as he smiled. His thumb ran back and forth over her soft skin as he raised his gaze to meet hers, eyes shining with excitement as a wide smile split his face.

"Aye, I know. I felt it."
