There are a few comment fics. (http://sharp-teeth.livejournal.com/2807.html?thread=577783#t577783)One of them was extended and reposted as "Sam I Am." (http://metamorphagi.livejournal.com/56768.html) I haven't read the fic you mentioned, but it sounds cute -- these are dark by comparison, be warned.

dark ficc? ;3; I will read it! Since the fic I read was also a little bit sad. Anyways, thank you so much for the rec! :D

Well, this isn't quite what you asked for, and it also happens to be by kellifer fic - but it kind of fits - so here you go: (er, and read it through - it's not quite what it looks like. And it isn't long.)

Excerpt
Dean woke to a little boy curled into his stomach. He messed his hand through a mop of fine brown hair before he really woke up and realised that something was wrong.

“Sammy?” he hazarded and the little boy turned over and blinked large hazel eyes at Dean before a huge yawn swallowed half his face.


“No fair,” he grumbled. “How’d you get so big, Dean?”

<3 I've read this one, but can't remember the finer details. :D Thank you for the rec! -runs off to reread-

'Three foggy mornings and one rainy day (will rot the best birch fence a man can build)' is one of my faves.
http://britomart-is.livejournal.com/156805.html - Mary Winchester has one son.

I'm sure there's more but my minds a blank right now.

;__; that story was heart breaking and amazing! Thank you so much for the rec!

There's "The impossibility of we" by Charlotte and Brie:

Since he was born Sam's had a companion no one else could see, a guardian, a presence he just doesn't know how to be without. His Dean. As he gets older it becomes a challenge to understand how this companion - never seen by anyone else but perfectly real to him - can still fit into his life and what he wants.

<3 looks interesting! thank you for the rec!

I love this fic by paperbkriter- What Was and What Will Be: http://www.fanfiction.net/s/3724345/1/What_Was_and_What_Will_Be

I hope it matches what you're looking for!

Dude! This was exactly what I was looking for! Thank you so much! It gave me chills! <3

Awesome! :D
