“Twins” born years apart…

Every so often there’s an article like this one in today’s Guardian, about “twins” born years apart… The writer of this piece has a son and daughter born as a result of one fresh IVF cycle and a further frozen embryo transfer from the same batch of embryos.

It is a fortunate, yet far from uncommon, experience after fertility treatment, but it doesn’t make the children “twins”. Twins are two babies who are carried together and born at the same time, which these children were not. They are siblings rather than twins.

The Guardian seem to specialise in this myth – here are some previous twins who were born five years apart, although at least that time they called them “twins” in the headline…  Those were also covered by the Telegraph. And unsurprisingly the Daily Mail likes them too – these brothers born two years apart are “technically” twins according to the Mail – in fact, they are technically not twins. It is always made to sound as if it is some extraordinary and highly unusual matter, yet there are hundreds of thousands of siblings around the world who will have been conceived in a similar way.

Maybe I’m getting pedantic in my old age…
