Another necessity, if you're considering having baby bunk in your room, is a co-sleeper. The American Academy of Pediatrics discourages co-sleeping -- but with one of these handy infant beds (which securely fits against your bed), you can have Baby close by and still sleep safely.
Niceties: Cradle or bassinet.
The plus side is that a cradle or bassinet is compact and portable, but babies outgrow them very quickly (and can sleep in a crib from day one).
It's important to use sheets specifically made for cribs, and that fit tightly and securely around the mattress. Invest in top-of-the-line sheets designed to stay tucked.
Niceties: Fancy bedding items.
Consider passing on: Matching bedding sets (bumper pads are cute but not needed for baby's comfort, plus quilts and pillows can't be used in the crib for safety reasons), mobile (a wind-up version that plays music can be a great soothe-to-sleep tool, but make sure it conforms to safety standards).
