@writerjayne, I'm sorry this took so long, but as promised, here is the list of my favorite fics in which Derek possesses some grade-A childcare skills. I tried to keep as on theme as possible with Derek having the better childcare skills between him and Stiles (or anyone else for that matter), or where he at least has better skills than anyone expects him to, but I may have deviated just a little bit. I also tried to avoid any non-canon AUs just in case that isn't your thing. Hope you enjoy!
The Evolution of the Egg Baby Assignment by minusoneday (G | 1/1 | 2,941)
At the end of the period, Mr. Wilson hands out the babies and lets the students get into their pairs to discuss their caretaking plans.
“Okay,” Stiles says, once he settles into the desk beside Lydia. “So, I was thinking - ”
“I’m going to stop you right there,” Lydia says. “Children are not in my ten-year-plan. Children are not in my twenty-year-plan. Therefore, we’re going to structure this assignment as if I’m the successful math genius I fully intend to be, which means I’ll be out of the country at a math conference for the duration of this baby thing. Have fun raising our child.”
David Hale, Matchmaker by Menacherie (NR | 1/1 | 3,222)
Chris doesn’t know about the baby. In fact, Laura doesn’t even know until they’re safe in New York with their normal and safe aunt and uncle. Laura doesn’t tell him either. (It’s not until years later, when Derek sees David’s blue eyes staring back at him through Chris Argent, that he has an inkling of who the father is.)
Derek doesn’t say anything, but it’s ironic that Kate Argent burns down the house of her own unborn nephew.
You And Me (Baby Makes Three) by clotpolesonly (G | 1/1 | 5,493)
Pulling out his phone, Stiles said, “I’m sure dad’ll be thrilled to be woken up at two in the morning for an off the books amber alert, but he’ll suck it up.”
He’d only taken a few steps away before Derek said his name. Stiles turned back to see one of those little grabbing hands reaching out for him. Her eyes were brown, apparently, when they weren’t glowing, and they were wide and wet and looking up at him beseechingly from Derek’s arms, and Stiles couldn’t walk away from that.
The One Where They Adopt a Selkie by mikkiemouse (T | 1/1 | 7,737)
"That's a kid," Stiles said.
Derek growled. "It's a selkie."
"It's a selkie kid," Stiles pointed out, because really, they did not need to be arguing semantics right now. "Do selkies just go around leaving their kids sleeping in caves on the beach?"
Christmas Kisses by HappyJuicyFruit (G | 1/1 | 8,621)
After ten years away, Derek returns home to find a very different Beacon Hills than the one he left.
He decides it’s much, much better this way.
Derek, Did You Steal That Baby? by SylvieW (M | 1/1 | 10,119)
When Derek suddenly shows up with a baby, everyone is suspicious. Except for Stiles. He doesn’t care where the baby came from, he just wants to play with her and explore the new side of Derek she brings out.
god was a dog-man by spqr (T | 1/1 | 12,810)
“Do you have a secret teenage son?” Stiles demands, as soon as Derek opens the door.
Five Days and a New Moon by LadyDrace (T | 1/1 | 13,614)
Stiles gets a visit from himself from a parallel universe. In which he was born a girl. And had a kid. Which he's now stuck taking care of for a few days.
Oddly, though, Derek seems totally happy babysitting.
A story where things are both more joyous and more sad than anyone really expected with a such a cute baby involved.
omnis cellula e cellula by twnkwlf (E | 3/3 | 15,302)
“You put the diaper on backwards,” Derek says.
What to expect when you aren't expecting by MemeKon (T | 1/1 | 16,921)
The baby's wailing is piercing, Stiles doesn't know how Derek can stand it. He tries shushing her and cooing at her and bouncing her a little, but the crying only gets louder, and in addition to hurting his ears, it's hurting his soul.
“Stiles,” Derek interrupts him mid-croon, eyebrows meeting over the bridge of his nose, “have you fed her since you found her?”
Stiles gapes and looks down at the baby's distressed face as she bawls.
Blood and Bonds by ProofOfConcept, wilddragonflying (NR | 1/1 | 20,595)
Stiles wants to lose his virginity, so Derek sets him up with a nice female werewolf at a pack mixer. Nine months later, the pack gets a rather stark reminder, and with it comes realizations, feeeeelings, and danger.
How Derek Met His Smallest Fan by purpleduvet (maga_nw) (M | 2/2 | 37,273)
Derek is standing in the fruits and vegetables aisle, trying to decide between two very nice looking watermelons, when someone small crashes into his legs.
Derek comes back to Beacon Hills after years of being gone and meets Stiles and his kid at the supermarket.
The Accidental Hale Brood by Julibean19 (M | 1/1 | 42,370 )
“I know, I just…” Derek trailed off, rubbing his forehead with both hands, frustrated that the right words weren’t coming to him.
“What?” Stiles asked honestly, pulling on one of Derek’s wrists until he could see his expression again.
Derek’s heart pounded in his chest so loud he figured even Stiles could hear it. He inhaled deeply and let the air out slowly through his nose, trying to keep his voice even. “When we take them places, and spend time with them, and make them smile… it feels like…”
“It feels like they’re yours,” Stiles finished for him, licking his lips before snagging the bottom one between his teeth.
“No,” Derek said, taking Stiles by surprise. “It feels like they’re ours.”
“Oh,” Stiles said simply, mouth still slightly open while he contemplated Derek’s words.
Or, the one in which Stiles and Derek have been BCPD partners for years when they are assigned Halloween duty and run into a couple of kids from the orphanage. One fake marriage and two real adoptions later, they somehow become a family.
The More That I Know You (the more I want to) by LadySlytherin (M | 1/1 | 43,656)
When death, in the form of hunters, comes for a family of Kelpies seeking refuge in the Preserve - in Hale territory - the Hale Pack is too late to save them. Before he dies, the male Kelpie presses a precious bundle into Stiles’ arms and begs the Emissary to take responsibility for it, which an initially reluctant Stiles does. When he agreed, Stiles had no idea what the sight of him with a baby would do to his esteemed Alpha, Derek. If he’d known, he might not have been so reluctant to agree.
I Know Where Babies Come From, Derek by DiscontentedWinter (M | 15/15 | 51,937)
Stiles finds a baby on the porch.
It looks exactly like him.
