A/N: Sorry for the wait. Finals happened, and then it was time to go home for break. I temporarily lost my train of thought with the story, but I've found my place again.

Enjoy!

Sherlock had to make a nappy-run when Adeline was a week old. When he returned, he found Irene lying on the couch, staring up at the ceiling despondently. Madeleine was lying next to her protectively, pleased to be back with her owner. "Is everything okay?" he asked tentatively.

Irene sighed. "I miss her," she answered.

"Who?"

Irene turned to look at him. "Addie. I miss being pregnant. I don't like that I don't know what she's doing anymore."

Sherlock furrowed his brows. Adeline was in the cot next to the kitchen, asleep. "Of course you know what she's doing. Right now, she's asleep."

Irene smiled wanly. "It's not that… I mean… I don't have control of where she is anymore. It was easy taking her with me, but now, she's independent of my body, and I miss that."

"You complained about the backaches and how fidgety she was."

"Of course. It wasn't always comfortable, but I still miss it."

Sherlock thought for a moment. He stepped into the kitchen and set the nappies down on the table and then moved over to the cot. He picked Adeline up from her cot, to which Irene made a noise of displeasure. "You're going to wake her up!" she hissed.

He ignored her protests, and carried Adeline over to Irene, placing the baby down on Irene's abdomen. "It might not be what you're talking about, but at least she's in the same general area," he explained.

Irene knew that she was going through a bout of postpartum depression and that Sherlock wasn't exactly socially adept enough to figure this one out. Fortunately, she was working with John, who had noticed that Irene had the symptoms of postpartum depression a few days earlier, so Sherlock's menial ability to help Irene through this wasn't going to impact her recovery. She was touched by his rather simple solution to Irene's problem, and quite honestly, she was glad to see that he was able to think quickly in response to emotions. She didn't think that he was able to react so quickly to reactions like this in the past.

But, ultimately, it was nice having Adeline sleeping on her instead of in a cot across the room. Sherlock didn't know it at the time, but he had just inadvertently started a new practice in the household: naptime on parents.

Irene's depression eventually decreased and she was finally deemed ready to go about six weeks after she had Adeline. Though she still talked to her psychiatrist on a weekly basis, wanting to take preventative measures in case it came back, things settled out nicely and they fell into a nice pattern. Adeline had some trouble sleeping in the beginning, but it was Sherlock who figured out that she didn't like being in the cot at night and slept better if she was in bed with them. Irene had originally protested this, but Sherlock had pointed out that it would make nighttime feedings a lot easier if she was only a matter of inches away from Irene, rather than a few feet away.

When Adeline celebrated her 10-week existence, Sherlock and Irene received a call from John informing them that Mary had gone into labor and that he would call when the baby was born. Colin William Hamish Watson was born two weeks early, weighing in at about nine pounds and was 21 inches long. Upon hearing this, Irene shuddered at the thought of delivering a child that was the size of Adeline at two and a half months old.

John, of course, was absolutely ecstatic about his son. When Sherlock and Irene arrived at the hospital, Adeline in tow, he practically thrust the baby into Sherlock's arms and started jumping for joy. Irene looked alarmed, Sherlock was startled by the sudden presence of a newborn that wasn't his own child in his arms, and Adeline yawned.

"What's his name?" Sherlock asked after congratulating John and Mary on their child.

"Colin William Hamish Watson," Mary answered.

Irene smiled. "Lovely name," she assured them.

She was standing near Sherlock, examining the small (actually quite large for a newborn) baby while holding Adeline. But, it was not Sherlock or Irene who had the most telling reaction to the baby. Adeline was thoroughly unimpressed with Colin; her general disinterest was most prominently observed when she sneezed on him. And thus started the very interesting dynamic between Adeline Holmes and Colin Watson.
