Have you ever wondered why you were blessed with twins, triplets or more? For many, it’s down to chance but there are some things that could make you more likely to be told it’s more than one!

  • You are more likely to have twins, triplets or more if there is a maternal history of multiple pregnancies. The influence of the father’s family history is less clear.
  • If you already have fraternal (non-identical) twins, then you are 5 times more likely to carry multiples in your next pregnancy.
  • Multiple pregnancies are more common in older women.
  • Heritage/race can be a factor in whether you have more than one as some countries have higher rates than others.
  • And finally, did you know? The more pregnancies you have, the higher the chances of having twins or more.

ONS latest figures show that in 2018 there were 10,005 UK multiples births, that’s 9, 873 sets of twins and 123 sets of triplets!
