The different types of twins

You are most likely to have either identical

or fraternal twins, as these are the most

common.Fraternal twins are known to be

hereditary whereas identical twins happen

spontaneously

Fraternal twins, also known as dizygotic, occur

when two eggs have been produced by the mother

and then fertilised by two sperm, leading to each

twin having its own placenta.

The twins can be the same sex or different sexes

and look no more like each other than other

siblings in the family.

There are in fact more fraternal twins born than

identical twins.

Identical twins, also called monozygotic, are

created when one fertilized egg (zygote) splits into

two separate embryos. These twins are the same

sex and usually look very alike as they share the

same DNA.

Identical twins often share the same placenta.

MYTHS About PREGNANCY

  6 labour myths DEBUNKED Here we look at some popular misconceptions about labour and birth and give you the facts. Myth 1. When you are due, home remedies such as drinking castor oil, eating curry or pineapple will help to get labour started. The thought behind this is that these will stimulate the digestive system, and in turn the uterus, but there is no evidence that any of these will work. You are much more likely to end up with diarrhoea or heartburn. Myth 2. Having a ' show' means you are in labour. A ‘ show ' is when the blood-tinged plug of mucus that has been protecting your uterus from infection during your pregnancy is discharged from the vagina. It can appear as a single blob or in several bits. Although a show is a sign that the cervix is softening, it doesn't mean that labour has begun. Labour may not start for a few days, and in some cases, a few weeks after a show. Myth 3 . Your waters breaking will be dramatic Having your waters break unexpectedly in...

What to expect during LABOUR

  What to expect during labour It's natural to be concerned about how you will cope with labour, but one of the best ways to overcome any anxieties you may have is to find out as much as you can beforehand. Here we explain what happens during labour and tell you about your pain relief options. A first labour usually lasts for anything between 6 and 20 hours, while any subsequent labours are often much shorter. During labour you will go through several stages and it helps to know what happens in each so you can recognise the signs that you are progressing, Early labour (latent phase) This can take hours, or even days as contractions start to build up. Unless there's a medical reason for you to go early to hospital, you'll be much more comfortable at home during this stage. Initial contractions are short and irregular. During this time you may experience a ' show'. Try to rest and stay relaxed when you are in early labour, even if you can't sleep. Having a warm ba...

More than two babies

  More than two babies Identical triplets occur in almost the same way as identical twins, but instead of the egg dividing once, one of those halves divides again to create three genetically identical babies. If three eggs are released and each one is fertilised by a different sperm the babies are fraternal triplets. Triplets can often be a combination of identical and fraternal – two identical and one fraternal. This means that two eggs are released by the mother and fertilised, and then one splits to form identical twins.
