Ok.... bottles not if you plan to breast feed only get them as you need them
Baby powder I'm not a fan it's up to you
Rocker/bouncer/swing: it's up to you...
Breast pump only if you are planning to express ie if you are going back to work
Cot sheets would probably go with half a dozen as they are very handy to have.

Most stuff you can do without I found I had the bare minimum and just picked things up as I needed them.
