I have a bunch of parent!Dean fics on my delicious (https://delicious.com/surrealdream93/parent!Dean) I think only some of them are of him as a single dad, but I have all my links pretty well tagged so you can usually check the tags for any pairings you don't like :)

Perfect! Thank you :)

I hope you don't mind self-recs but I wrote a single parent Mpreg Dean on Fanfiction.net; This story has one more chapter left and then I will be writing a sequel that has his kids a little older and his life with them while dealing with the appocolypse.

Sounds awesome, thanks!

Are Dean/OC fics ok? My writing partner and I write a curtain!fic verse where both Sam and Dean have settled down with families of their own. Some of the fics are posted on my ff.net page (http://www.fanfiction.net/~kadysn). Feel free to read whatever you like there. Just read the summaries for the ones that are more Dean-specific. These fics are definitely laden with schmoop.

Great, thank you!

The Shattered One by MissAnnThropic. AU after 05x08.
Summary: When it struck Castiel, he was in mid-flight. It dropped him out of the sky like a sparrow buffeted by gale-force winds. Castiel set down the first place he could find. He ended up standing in a field in Switzerland, swaying on his feet and staring down at his body, dazed by what it had just done. (mpreg)

Wow, thanks!

This one had Dean as a teenage dad with Sam as the father. It's also a j2 fic.
Destiny Always Finds You (http://mpregloveranon.livejournal.com/21837.html)
Jensen is driving home after working a long, exhausting shift at the ER. He just wants to spend a little quality time with Jared and then sleep but apparently destiny has something else in hand for him.

Oh! I forgot all about this fic but its a favorite of mine, thanks so much!

Paternal Evolution by faithdaria. Past Dean/Lisa
Summary:Dean Winchester gets a phone call that changes his whole life.

My absolute favourite Daddy!Dean is This Christmas Day (http://tolakasa.livejournal.com/2388.) by tolakasa. Dean and lots of children!

I am also very fond of ficwriter1966's Hope Verse (http://ficwriter1966.livejournal.com/178500.html#cutid1) which is the ongoing adventures of Lizzie, her mum Morgan and the adopted dad that Lizzie found for herself.

In Firefly (http://www.fanfiction.net/s/4646247/1/Firefly), Dean discovers he has a 4 year old daughter when her mother dies in a fire.

Thank you!

Road, You Gotta Take Me Home

Summary: After his ex-girlfriend is killed in a car accident, Dean gains custody of her fourteen year old son. They know it’s going to be difficult, with the stress of grief and unfamiliar living conditions weighing on them, but neither of them is ready for just how difficult it really is, trying to feel out where they belong in the confusion and aftermath of such a great loss. They deal with it though. They’re family. What other choice do they have?
A family drama, featuring Dean as a new single father, Ben as a ninth grader with trouble coping, Sam as the voice of reason and the rock that holds Dean up and Cas as the sympathetic police officer who repeatedly busts Ben for petty crimes.

It does have some Dean/Cas in it, but it's mostly about Dean and Ben.

Thanks

I see the moon (http://kaylennz.livejournal.com/4828.html) by kaylennz (http://kaylennz.livejournal.com/) is a pretty amazing Daddy!Dean fic. It's starts off as a Dean/ofc fic but the ofc dies, Dean ends up as a single parent and Sam and Dean eventually become a couple.

Thank you :)
