is breastfeeding twins really that uncommon?

I know the LCs at both hospitals my boys were in "warned" me that twin moms usually have to start supplementing at some point. However, I pumped exclusively for the first month, and then slowly transitioned them to breast. I do take supplements to keep my supply up, but the boys have been breastfed for four months now and no plans or signs of stopping!

I do think it's not the norm in general for women to EBF twins, but online, I see a lot more of it. I think because there's so much information and support online.
