We bought a new car seat for DD1, DD2 went into her old one. One special outfit for coming home in. I bought a new carrier (beetlebums) and sling (breeze) as I had passed my old ones onto others.

Didn't bother with a double pram, I wear DD2 and DD1 uses a stroller or walks. As DD1 (3 next month) walks more and more, the stroller can be used for DD2.
