1) Carseat cover

3) extra bottles? ( we have 6, 3 lil ones, and 3 9oz) not sure weather to get more or wait to c if baby will take the ones we already got

4) paci clips

5) diaper bag (i have a backpack that fit everything we need for hospital but its not a diaper bag)

6) crib set (we have quilts made for us and alot of sheet and mattres protectors)
