Twin Birth

As with any pregnancy, women with twins need to carefully consider their delivery options. Dr. Colin Walsh is highly experienced in both vaginal and caesarean delivery for twins and will help you make the best decision for you.

It is often helpful to have a preliminary discussion about birth preferences early in the pregnancy and then reach a definite decision at 32-36 weeks, when further information about fetal growth is available.

Timing of birth

  • It is recommended that uncomplicated dichorionic twins be delivered at 37-38 weeks. Uncomplicated monochorionic-diamniotic twins should be delivered at 36 weeks.
  • Although much less common, triplets and monoamniotic twins require care by a fetal medicine specialist. Triplets should be delivered by 34 weeks and MCMA twins at 32 weeks.
  • Twin pregnancies complicated by fetal growth problems, pre-eclampsia or gestational diabetes will often require earlier delivery. In addition, more than 50% of women carrying twins will labour spontaneously prior to 37 weeks.
  • As a multiple pregnancy expert, Dr. Walsh will be able to advise you on the best timing for your twin pregnancy.

Mode of delivery

Women expecting DCDA and MCDA twins can usually try for a twin vaginal birth, provided that Twin 1 is in a head-first position and there are no major fetal growth concerns. Of course, some women prefer the certainty offered by an elective caesarean section, which is always reasonable in twin pregnancies.

There is a small (<5%) risk of a successful vaginal birth for Twin 1 but then requiring an emergency CS for Twin 2.

Women expecting triplets or MCMA twins should always have a caesarean delivery.
