Raising twins!

I was just wondering,

if you have twins, were you able to breastfeed them without formula? And how?

Did you have to do everything for them at the same time? Or each was different time?, for example, feeding, sleeping, changing ..etc

And what was the hardest thing of having twins starts from pregnancy - giving birth- raising.

And what was the best thing of having twins starts from pregnancy- giving birth- raising

If you’ve been under any experience that you learned from or any advices i hope you can comment for all new mama’s to be or first time having twins!! I would really appreciate it
