A/N: I'll try to make this as short as possible, but basically an episode of Torchwood got me thinking (SPOILER). When Martha showed up on TW and went undercover and her blood work came back mutated, it got me wondering if that would cause fertility problems, and then (SPOILER FOR SEASON 7) when Amy told Rory she can't have kids, I really felt compelled to write this.

Disclaimer I own nothing Doctor Who related.

Any advice, concrit or reviews would be greatly appreciated :-)

Prologue

Her strawberry curls bounce in the late afternoon sunlight as she races across the grassy field.

She climbs over the back garden fence and comes to a skidding stop at the back door.

She peeks in the back window to make sure the coast is clear before sneaking in the back door.

She's just about to breach the first step when her mother enters the kitchen, her slightly swollen belly entering a millisecond before her.

"…and where have you been, young lady?" She asks her daughter. "I thought I told you not to leave the garden."

"Awww, mum," She wines as she turns to face her. "I was just over the garden fence, in the field."

"And is that in the garden?" She asks placing her hands on her hips. "And where are your shoes? Look at the state of you; knees skinned up, feet as dirty as a pig's pen."

She lets out a heavy sigh. "I was just climbing the trees in the back field, mum. I climb better without my shoes; they're still in my room."

Her mother lets out an equally heavy sigh. "For the love of…sweetie, you're 7, can you please just stay in the back garden as you're told? You shouldn't be wandering off like that."

"Almost 8." The little girl mumbles under her breath.

"Best do what your mum says, curly Sue." Her dad says entering the kitchen, bespectacled, with a folded up news paper tucked under his arm.

"Daaaaaaaaaad. Please stop calling me that."

"Never," He smiles and rumples her hair. "Now better run along and get cleaned up."

She sighs, but trudges up the stairs.

He watches her go. Just before she reaches the top of the stair case she turns to look at him and he winks at her.

Her face splits into a grin and the tip of her tongue pokes out between the gap where her two front teeth are missing.

A smile all tongue and teeth. Just like her mother.
