Twin Girls: What you need for the first month
I've never had twin girls (I wish!) but I would imagine you need the same things as you would for a singleton baby, just double of everything!
- a place for them to sleep
- diapers & wipes
- a few outfits - I loved the little gowns as they made diaper changes easy
- a way to feed them - either breastfeeding or bottles/formula
- car seats so you can take them home from the hospital, and to their doctor appointments
That's really probably all that you NEED. There are a lot of other things that may make things easier on you as a parent - a swing, bouncer, pacifiers, white noise machine, etc but a baby actually NEEDS very little.
