Do I Need Two of Everything When Having Twins?

You don't need two of every item. I would say, as a mother of multiples, you do need two of some things. That would include a crib, car seats, and for sure a double stroller so you have the ability to leave the house if you need to by yourself. There are a lot of other items that can easily be shared, a bouncy chair, a swing, and an exersaucer.
