What to prepare for?

I just found out I'm having identical twins; one gestational sac, two yolk sacs. Couldn't see the membrane yet but they're thinking monochorionic diamniotic twins.

What do I need to prepare for mentally in this pregnancy? And what Tips do you have for newborn stage. I have 3 singletons, so know my way around a newborn. But two? That's a challenge haha. 💖💖💖
