Hope (http://septembers-coda.livejournal.com/5845.html)
Sam’s got his soul back, but it’s not easy living with what he did while his soul was trapped in the Cage. When one consequence of his lost year lands in his lap, the Winchesters’ whole world is thrown into turmoil.

It Was a Dark and Stormy Night (http://winchesterpooja.livejournal.com/20650.html)
He sighed. The eyes, the dimples, the stubborn crankiness… they had a mini, female Sam in their hands. This was going to be hard.

Sam's soulless days come to catch up with him and the Winchesters find themselves in a situation: Sam has a toddler daughter. There are difficult times and sad times, and then there are times with cuddles, bathtub babbles and wild ponytails on Sam's hair. He realises this might be the best and worst thing in his life all at once.

Finding Normal (http://annie-46fic.livejournal.com/269815.html)
Sam finds out that there is something else Ruby was hiding from him. Can he & Dean make a home for the child he never knew he had? He might have cured his brother once but the Mark of Cain still haunts the Winchesters and it's dark shadow hangs over every move they make. Sam wants to keep his daughter but, deep down, he knows he will never 'Find Normal'
