FTM with twins.

Whitney
I'm 19 weeks with boys. I have lots of questions. Like, will I need two bassinets? Will I need two or everything? Will they even use a crib? Can they both use one? 
So far, I have two cribs, two swings, and a bouncer thing that you sit on the floor and vibrates. I bought some cloths also. But how much do I need exactly?? The doctor told me at my scan the other day they are already 10oz each.
