What do I need for twin babies?

Furniture wise I would only purchase 1 of all the major things. You may, however need 2 dressers because the clothes quantity is x2! Odds are your babies wont be using the bouncers, binets, swings, chair, and changing tables at the same time! Just because they are twins does not mean that they will do everything at the exact same time. Every baby is different. 1 diaper bag is sufficient, just make sure it's a good sized one with plenty of supply in it! Always carry at least 3 bibs, burp cloths and burp pads on hand. It all depends on how often these things are used by your babies. I would only buy 3 different kinds of pacifiers per baby, they might not like the same kind. They also may not even like to use a pacifier. I'd say start off with 15 bottles. Good luck and I hope this helped!
