Will it be obvious if my babies are identical when they’re born? What’s the difference between identical and non-identical twins? Identical twins always develop from a single fertilised egg that’s split and grown into two, genetically identical babies. Non-identical fraternal twins grow from two eggs, separately fertilised by different sperm.
You’re sure to be keen to find out if your twins are identical, but your obstetrician and midwife will be too. Whether or not your twins are identical can affect the type of medical care you and your babies receive. It can also affect the type of birth you have. Defining twins, whether identical or not, is more complicated than you may think. Medical definitions of twins are based on how the twins are conceived – from one fertilised egg or more – and how they are growing in the womb uterus.

Fine, if your intention is just to avoid hospital – but if you are concerned about interfering with your body’s ability to give birth, then DIY methods might not be right for you. If your baby is not ready to be born, in a difficult position , or your body is not ready to go into labour, then DIY induction might bring on a weak pre-labour which peters out. If this happens, and you have already informed your midwives, then you might find yourself under pressure to go into hospital for acceleration of labour, or you might find yourself tired out by the time true labour begins.
DIY labour induction has worked well for many women, and may work for you – but do be aware that it is an intervention, albeit usually a gentler one than hospital induction, and it may well alter the course of your labour.
