Sometimes l think they tell parents too much too soon. My youngest daughter had scan for viability with her youngest Daughter at just 8 weeks. They told her shewas expecting twins, and everything looked Ok. At the next scan at 12 weeks, one of the babies was no longer visible, and had been reabsorbed in what is known as a spontanious sterile abortion, natures way of dealing with a less than perfect foetus at a very early stage, although the other twin went on to be delivered at 36 weeks as a beautiful tiny baby girl, weighing 5lb 2oz.
My daughter to this day still mourns the baby that she lost, and wonders if it would have been a boy, as she now has three girls. Without that very early scan, she would have been totally unaware of a twin pregnancy, and spared the upset thoughts of the baby she lost and what they would have been like today.
