Actually there is some evidence that the rate of morning sickness is slightly higher with twins. That’s the rate though. Many more mothers of singletons get morning sickness.
I’m wondering if Kate had IVF??
I did not know that before I skimmed this article. My criticism is that the writer jumped right on that fact to speculate that twins were on the way.
Why do you wonder about IVF? Is there also increased morning sickness?
IVF would be a last ditch effort. She’s only 30 and they’ve only been married a year and a half.
