This one springs to mind:
Cowboys and Babies (http://archiveofourown.org/works/81811?view_adult=true) Jared's ancient Taurus dies not in a blaze of glory but with a pathetic wheeze and a tiny shudder by the side of the road miles and miles away from any kind of civilization. He puts his head down on the steering wheel and inhales shakily, talking himself out of crying. He knows it's just the hormones but combined with everything that had gone down with Chad days earlier and not having anywhere to go but back to his momma and dad who were not happy about his decision to keep the baby, husband or no, it's just all too much to take.

So when the car dies, Jared feels like curling up by the side of the road and joining it.

You know, I think I vaguely remember this. Thanks for the response - it could do with a reread.

Hi, perhaps you like to try these.

(Sorry, this one is going to winchest. Dean has a dauther by his own.)

The next both are not exactly what you ask for, ´cause adoption storys (kind of).

Thank you

I read Home in Motion a few months ago and really enjoyed it - thanks for the reminder.

There's this one: http://memphis86.livejournal.com/125317.html

Thanks!

I don't know if you have read this..but it's really sweet mpreg where Jensen meets Jared when he's already pregnant and falls in love with him.

2) It's sequel - Imaginary Spaces - Jared (http://storyspinner70.livejournal.com/9808.html)

SUMMARY - When Jared, his toddler, and his baby bump move next door to Jensen Ackles, Jared finds out exactly how much a life can change.

3) It also has a timestamp - Imaginary Spaces - Tom Visits His Daughter (http://storyspinner70.livejournal.com/10362.html)

SUMMARY- When Jared, his toddler, and his baby bump moved next door to Jensen Ackles, Jared found out exactly how much a life can change. But what caused them to move in the place?

This MIKEY VERSE (http://storyspinner70.livejournal.com/tag/mikey%21verse) is incredibly touching and heart warming and one of my favorites...

Thank you : )

These may not be exactly what you're looking for, but...

Dawnbringer!verse (http://archiveofourown.org/series/26846), by lexicale is pretty amazing. It's J2 were!fic and mpreg. Jared starts out raising a baby/kitten he finds in the wild, which turns out to be Jensen's (not from mpreg). Then Jensen has to learn to be a father to his own child, that someone else has 'adopted'. Plus, all kinds of other awesome, exciting things happen :)


Also, if you don't mind self recs I wrote a couple of 'raising kids that aren't yours' stories a while back.

Road, You Gotta Take Me Home (http://archiveofourown.org/series/26846)
Dean/Cas AU. Lisa dies and Dean ends up raising Ben and starting a relationship with Cas.

Ice Is Slowly Melting (http://archiveofourown.org/works/831254)
J2 AU. Jensen has a son (with Misha, from a previous het relationship). Misha 'dies' and Jensen and Jared get together and they deal with where Jared fits into the family and his role in the kid's life.

Thank you - I've enjoyed the Dawnbringer Verse a couple of times, but I have not tried the others.
