A/N: My first fanfic (that's not a poem). I've been reading some HPFF so I decided to do some of my own. SiriusxHarry (not slash) is my favourite... So, here you go! A one-shot, tell me what you think! (Go easy though, it's my first time!)

Who's Harry's Mama?

Little baby Harry was in a giggling fit. His godfather, Sirius Black, was throwing him high up in the air, catching him, and then repeating the process. Lily had a fit at first, threatening Sirius a variety of pain and torture if he ever dropped her boy. Eventually she stopped worrying. Sirius loves the boy too much to ever drop him, she thought to herself.

During Sirius's and Harry's little game of "Throw, fall, catch", James Potter apparated in the living room. He smiled at the sight of his little man laughing, giggling, and most certainly NOT crying (he was releived about that).

"Prongs!" Sirius exclaimed, catching Harry and pausing the game. None the less, Harry was still giggling like a crazy person.

James quickly walked over, said his hello's to Remus and Lily, who stopped making dinner, and stood in the living room to watch Sirius and Harry have some fun.

James took Harry, rocked and cooed towars him (receiving a gag from Sirius). Hyprocrite, James thought. He's seen exactly how fatherly Sirius can get with Harry, and James knew he made no mistake apointing Sirius Godfather.

The next two hours went well. They cooked and ate dinner. Or, rather more precisely, Lily and Remus cooked dinner, while James and Sirius played with Harry.

It was almost time for Harry to be put to bed when James started trying to get Harry to talk.

"Come on, Harry, say it." James said, sitting on the ground next to his boy, "Dad-dy." He sounded out in two syllables. Harry said nothing, instead, he stared at his father.

Sirius laughed, "You're doing it wrong, Prongs!"

"Oh? Loved to see you do better, Padfoot!" James challenged, glaring at his best friend.

"Not now boys, Harry has to go to bed." Lily said, walking into the living room with Remus, who just finished cleaning up the dishes.

Sirius looked at the clock hanging on the living room wall. "Bloody hell, it got late!" Lily glared at him-she didn't care for his cursing, especially not around Harry. "I'll take him up to his room." Sirius offered, standing up from the rocking chair in the corner.

Hearing no objections, Sirius took this as an 'alright'. He walked over to Harry, picked him up, and was shocked by what Harry said next.

"Mama!" Harry said excitedly, staring at Sirius with a grin. Everyones' jaws dropped. He looked at James, who looked worried, then snuck a glance at Lily, who looked pissed. She had been trying for a month to get Harry to call her mother. Infact, she's done everything for the boy, fed him, clothes him, washed him, changed him, all without James's help, thinking it would get Harry to call her mother quicker.

"Uh... Maybe James should, uh, take care of Harry." Sirius said quietly, staring at James who stood up.

"Yeah," was all he said. James grabbed his boy and led him upstairs. He gave a worried glance towards Sirius.

"Now Lily, I know-"

"Sirius," she said, ignoring the fact that Sirius was speaking.

"Uh..." Was all Sirius could muster.

"Five seconds."

Sirius bolted to the fireplace, grabbed the floo-powder and hoped he make it in time. He didn't. Lily gave him a hard kick to the arse, causing the man to stumble into the fireplace. He yelled out his home's name, and flooed away, without anymore damage from Lily, luckily.

Remus watched in amusement. The child has some timing, that's for sure, he thought.
