Twin Facts

Some facts about twins:

  • It's more likely that your morning sickness will be worse.
  • More than 50% of twins are born preterm (before 37 weeks).
  • With a single baby, the average delivery is at 40 weeks, with twins it's at 35 weeks.
  • A single baby's average birth weight is 7 lbs, twins are 5.5 lbs on average.
  • You're twice as likely to get preeclampsia with twins
  • You're more likely to have gestational diabetes with a twin pregnancy.
  • One twin can be much smaller than the other because of placenta problems or because of twin-to-twin transfusion syndrome (when identical twins share a placenta and the twins pass blood between each other, making it uneven).
  • It's healthy to gain 25-35 lbs with a singleton pregnancy, but with twins 37-54 lbs is healthy. I need to be gaining 1 lb per week in the first half of pregnancy, and more than 1 lb per week in the second half. Yikes.
  • Because it's less likely for both twins to be head-down, C-section births are much more common with twins.
Now do you know why I'm a little stressed out?
