When Pamela Sutherland fell pregnant with twins, she was worried that people wouldn't be able to tell them apart.
But as soon as they were born at Elgin Maternity Hospital five weeks ago, she and husband Barry knew that it wasn't going to be a problem.
Because at 8Ibs 1oz, twin Daisy dwarfed her sister Poppy, who weighed in at just 5Ibs 7ozs.
It is the biggest size difference between twins ever recorded in the UK.
Mrs. Sutherland, 30, who lives in Portsoy, Aberdeen shire, with husband Barry, said: "We just couldn't believe it when they were born and they looked so different. Even the midwife was shocked when she weighed Daisy. "
A spokeswoman for the Twins and Multiple Birth Foundation said: "The size really is very unusual. We have never come across a size difference in twins as big as that before."
Size differences between twins can sometimes be caused by a condition called Twin to Twin transfusion syndrome.
Usually there is only a size difference between twins of up to 1Ib. Anything bigger than a 20 percent difference is considered a significant difference.
Mrs. Sutherland added: "They both have healthy appetites now, we weren't given the reason for the difference in their sizes, and we don't know whether they will ever even out and be the same size. Daisy may always be bigger than Poppy. But we don't mind. We are just thrilled to have，two happy healthy babies. We feel very lucky."


据英国《每日邮报》7月10日报道，当帕梅拉•萨瑟兰怀了一对双胞胎时，她还担心将来人们难以将孩子们分辨开。

但五周前，当这对双胞胎在埃尔金产科医院出生后，她和丈夫巴里就知道这不是个问题了。

因为虽说是同胞姐妹，妹妹波却比姐姐黛西矮小很多，黛西的体重是8磅1盎司，波比只有5磅7盎司。
这是英国有史以来体重差别最大的一对双胞胎。

与丈夫巴里同住在拉伯丁郡波特索依的现年30岁的萨瑟兰夫人说："我们简直不敢相信两个孩子相差这么大。当称出黛西的体重时，连助产妇都震惊了。"

双胎和多胎基金会的发言人说："像这样的差距确实很少见，我们还是第一次见到这种情况。"


"双胞胎输血综合症"有时候会引起双胞胎之间的大小差异。


通常双胞胎之间的体重相差仅仅在1磅左右，如果体重相差超过20％的就被认为差别显著。


萨瑟兰夫人还说："现在她们的食欲都很好，医生没能给我们解释孩子们体重差距大的原因，我们也不知道他们将来能否一样重，或许黛西会一直比波比大。但这些都没关系，能有这么健康快乐的宝宝，我们很激动，也觉得很幸运。"
