Video: Twins fight for the dummy

<p> Sienna and Sierra Bernal are <a href="http://www.parentdish.co.uk/2012/02/08/my-twin-sister-is-a-dwarf-sienna-and-sierra-bernal/ " target="_blank">identical twins</a>, but Sienna is half the size of her twin sister Sierra, as she has primordial dwarfism. The 13-year-old girls share the same coloured hair and physical traits, but tiny Sienna weighs half her sister's weight, and stands four feet tall to Sierra's 5ft 1in. Sienna is the only primordial dwarf in the world to have an average sized twin.</p>

Two were implanted in the twin's mum, Jody Blake, 38, which resulted in the birth of Reuben in 2006. The remaining three embryos were frozen until Jody and her husband Simon decided to try for another child. Floren then arrived on November 16 2011 - two weeks before her due date - but five years after her twin brother!</p>

<p> After spending &pound;70,000 on nine cycles of IVF, and clocking up 16,000 miles in a bid to be parents, Rachael and Mark Sadler are now proud mum and dad to twins <a href="http://www.parentdish.co.uk/2011/08/10/twins-after-nine-years-70-000-on-fertility-treatment-and-travelling-16000-miles/" target="_blank">Rebecca and Hazel</a>. &ldquo;I never accepted that I wouldn't be a mother.

<p> Beautiful twins Remee and Kian Hodgson share the same cheeky smile but Kian's skin is dark and she has black hair while her sister Remee is blonde with pale skin. The twins, who were born within a minute of each other, <a href="http://www.parentdish.co.uk/2012/03/31/beautiful-black-and-white-twins-kian-and-remee-hodgson-turn-seven/" target="_blank">owe their different appearances to a one in a million combination of their parents' genes</a>.

They didn't even know of each other's existence until 2003, and when they finally met in 2007, they believed they were only half-sisters. But they were struck by how similar they were and so decided to take a DNA test, which confirmed they were non-identical twins!</p>
