Author's Notes: Thank you to everyone for the wonderful reviews! I'm glad you're enjoying the story!

By the time Zoe was three months old, Greg realized why new parents were always so damned tired. The kid cried all night long and wouldn't stop until either of her parents was holding her. Allison finally gave in and took a couple of weeks off; she had the time, and Cuddy was insisting.

Greg went to work every day, looking more tired as time progressed. Chase couldn't resist poking fun at him, which resulted in Greg having three months off of clinic duty; Chase took it, and not at all like a man. He bitched the entire way, stunned when Cuddy even intervened, telling Chase that it was fair for him to take his boss' clinic hours.

Greg couldn't be more thankful. As he fell asleep over his lunch one day, Wilson came in and patted him on the back. "Kid keeping you awake?" he asked with a smirk.

"Fuck, Jim," he responded, rubbing his eyes in a feeble attempt to wake up. "She starts screaming for no reason in the middle of the night and she won't go back to sleep unless Allison or I hold her. Do you know how difficult it is to sleep while you're worrying about crushing this ten pound parasite that's sleeping on your chest?"

Wilson snorted. "I did it for a few months, so yeah. How's Allison holding up?"

"Just fine. She doesn't have to be in at nine every morning," he grumbled.

"But she has to breast feed. I think she wins."

He gave a grunt to show that he didn't care and tried to finish his lunch. "I want one night of full sleep. I'd kill for it."

"If Allison's okay with it, you can come and stay with me and Lisa for a night. Brian's finally gotten to the point where he sleeps through the night, so it'll be quiet."

Greg looked at Wilson with sad, hopeful eyes. "Are you serious?"

"Completely."

"I think I might love you."

"Don't tell Lisa."

"Don't tell Allison."

"Deal." Wilson sat in one of the chairs opposite Greg's desk and studied his friend with a grin. "So fatherhood isn't agreeing with you, I take it?"

He made a noncommittal noise and polished off his lunch. "I'll wait until Zoe's older and I can tolerate her."

"You love that little girl. I've seen you with her."

"She's cute when she isn't puking on me," he grumbled.

With a grin, Wilson leaned forward conspiratorially. "Learn the warning signs and hand her off to her mother right before she chucks."

Greg laughed. "Bet Cuddy loved you for that one."

"She fell for it every time. Moms have this … innate lack of a gag reflex."

Greg snorted. "They do. You should see Allison with Zoe. She changes a diaper without a second thought. I try to do it and find an excuse not to. We're doctors. We should be able to handle this."

"No, nurses should be able to handle this," Wilson replied. "We're doctors. We don't deal with feces and vomit most of the time. Techs and nurses do."

"And Fellows."

Wilson smirked. "And Fellows." He sighed and closed his eyes, dropping his head to rest on the back of the chair. "We're dads," he said slowly. "When the hell did we sign up for this?"

"You refused to simply be a donor and I thought with my dick instead of my brain," Greg muttered, signing a paper on his desk. He didn't even bother to read it; just signed. He ran his hands over his eyes and yawned again. "Can we quit?"

"No," Wilson said slowly, yawning himself. "But we can nap at work."

When House got home that evening, he was met with the picture of Allison on the couch, playing with Zoe by letting her pound on the keys of a play piano that he'd gotten her. He smiled and sat next to them, accepting the baby that was handed off to him and the kiss that greeted him.

"How was work?"

"Nice. I slept." He scratched and Zoe's belly to make her giggle. "We got a new case. I need you back. Chase's ideas are getting old and he's spoiling Foreman's."

Allison grinned. "Bring home the case?"

"It's in my bag." He turned Zoe to face him and glared at her. "I'm going to kiss you. And if you puke on me, your ass is grass." He leaned in and pressed a kiss to her nose, rewarded with another giggle before bouncing her with his good knee. "How's your vacation?"

"Wonderful. However, had I known I could get sleep at work, I wouldn't have taken the time off." She grabbed the case file and skimmed through it while Greg played with Zoe. "Check for endocarditis and encephalitis?"

"And vasculitis," Greg answered, holding Zoe up over his head and making jet noises. "No swelling, no temp, no infection. White count's normal." He set Zoe back down on his left knee and tried to keep her from feeling the stubble growing on his chin.

"Did she take any medications prior to being admitted?"

"Don't know. She won't talk. I'm sending Foreman to break into her place tomorrow." He cooed at Zoe and poked her nose, making her squeal with delight before blowing a spit bubble at him. "Don't steal any cars, okay Zo? I'm not paying your bail. You'll have to call Uncle Jim."

Allison snorted and continued to read the case. "These symptoms are constant with a reaction to either a medication that was filled incorrectly or an overdose."

"That's what I thought," he replied, brow furrowing in thought. "But then she started seizing and vomiting blood and things stopped looking so easy." He tossed Zoe in the air over his head and caught her. "I still think the meds are a part of it. But they aren't the big, bad wolf that we're looking for."

"Whatever the underlying condition is, it's been covered by whatever she took," Allison said, frowning as she read through the lab results. "Stop tossing her in the air, Greg. You'll drop her."

"I will not," he said, rolling his eyes and holding Zoe over his head, staring into the eyes that matched his so perfectly. "Your mommy's being anal again." He turned to look at his wife. "Why do you say the condition is being covered?"

"According to these lab results, it would have to be. She must've taken something to boost her immune system. No one's immune system functions this well. Is she on steroids, maybe?"

"She's a gymnast."

"I'd check for steroids."

"I'll have Chase do it tomorrow. Right now … I want to shower and eat dinner." He set Zoe on the floor and let her roll around, leaving his cane for her to play with.

Thanks to Allison's nagging, Greg had finally completed his physical therapy that he should have done years ago. He could now limp comfortably from one end of their house to the other without using his cane, but that was about it. He knew that it was better for him to be able to move at all without his cane, but he still felt that the months of physical therapy had been pretty much wasted.

He made his way to the shower, hearing Zoe squeal as she happily moved his cane along the floor. Who knew he'd actually … well … enjoy being a father? After his shower, he went to the kitchen, where Allison was already setting the table. "You work fast."

Allison smiled. "You know it. I'll feed Zoe when we're done eating."

"I still don't know how you can stand a kid sucking on your nipple for that long." He helped her serve the spaghetti that she'd made before sitting with her.

"It's not that bad. It's natural."

He smirked, digging into dinner. "You and that natural crap. If I recall correctly, you were the one screaming for an epidural."

She kicked his foot. "Shut up. I wanted to steal your Vicodin, I was in so much pain."

"Too bad. Drugs are mine." They ate in a comfortable silence, disturbed only by Zoe squealing from her playpen in the living room where she was watching some child television show that Greg hated. "Jim offered to let me stay with him and Lisa for a night."

"You're going to get sleep while I have to suffer?" Allison asked coolly. "That's sweet of you." She ate part of her dinner and took a drink of her wine. "You know, Zoe will be done crying every night in just a few weeks. You can suffer through it with me."

"Damn."

She patted his hand and went back to her dinner. "If you and Jim want to have a boys' night, that's fine. Send Lisa over here and you two can have a night all to your male selves. But you aren't getting off easy without me having some company."

"Fair enough. You and Cuddy going to have a baby-fest or something?"

Allison snorted. "No. We're probably going to let them play and talk amongst ourselves while we're tortured with reruns of The Wiggles."

"I hate that show," he muttered angrily.

"I know. But Zoe loves it. It's got bright colors and music."

Greg's pager went off and he grabbed it, glaring at it. "I need to go back," he growled.

"Let me come," Allison said simply. "I'll pack Zoe up and feed her on the way. I need to get out of the house, and I'll keep her away from the patient."

"You took a vacation," he pointed out.

"Come on," she whined. "I want in on this one."

He smirked. "Oh, fine. Pack up the kid."

They got to the hospital in no time, Allison just finishing up with feeding Zoe as they pulled into a parking space. "Put the boobs away, babe," Greg said with a smirk. "We've gotta work now."

She rolled her eyes at him and buttoned the top of her blouse. "Watch it or I'll bring them out during the differential."

He frowned. "I don't want Chase seeing your fun-bags. He's already seen them once… He doesn't need to see them again."

"You're so possessive," she sighed, carrying Zoe on her hip as they entered the hospital. "It's cute and frustrating at the same time." It was the first time since she'd had Zoe that she'd actually brought her to the hospital, and she wondered how Chase and Foreman would react. They certainly weren't used to having a baby around.

Once they got to diagnostics, Greg held the door for her. "I brought the immunologist," he said simply. "She thinks she can help. How silly."

Chase and Foreman both grinned when they saw their coworker with the baby. "She's gotten big," Foreman commented, looking at Zoe.

"Hey. Don't talk about my wife that way," Greg snarked.

Allison rolled her eyes and let Foreman hold Zoe. "So what's going on with the patient? He briefed me," she said, nodding to Greg.

"She started seizing and then went into cardiac arrest," Chase informed them. "But the arrest wasn't directly after the seizing. It was an hour later."

"That's weird," Allison commented, looking at the symptoms on the dry erase board. "And it proves my theory right."

"Which is?" Foreman asked, letting Zoe play with his tie, but preventing her from chewing on it.

"There's an underlying condition being covered by medications," Greg said, writing the new symptoms on the board. "Foreman, I want you to…" His voice trailed off as he saw the neurologist holding Zoe as if it were completely natural. He tilted his head to the side thoughtfully. "Chase, go to the patient's house and bring back any and all medications she's on." Once Chase was gone, Greg turned to his neurologist. "Foreman… What's your evening schedule like?"

Foreman looked suspicious. "Why?" he asked warily.

"Zoe likes you. You should baby-sit her."

Foreman almost choked in shock. "You want me to watch your kid?"

"Feel honored."

Allison grinned. "If you want to watch her," she said with a shrug.

"I've never really watched a kid… When do you need a sitter?"

"We'll let you know," Greg said. "Do you want to watch her for us?"

Foreman shrugged and smiled when Zoe tried to pull at his nose. "Sure."
