Sorry if I repeat anything that's already been said...
My daughter slept in our room for 6 months. The Fisher-Price Rock and Play Sleeper is the greatest invention ever. Sturdy, light, keeps baby strapped in, upper-body elevated, and on her back. Can easily be moved from room to room and awesome for travel. Once baby starts sitting up and wanting to turn over, it can no longer be used. I know many moms who've had it and loved it!
The moby wrap is great. Looks tricky but once you've mastered it it's perfect to keep a little one close by as you do things around the house and super for walks. My daughter was born in December. I took walks with her and was able to keep her snug and warm using the Moby.
We were paranoid about SIDS so kept our baby on her back most of the time. Then we were paranoid because her head seemed to be getting flat in the back. Doc ordered more "tummy time" but we also purchased a noggin nest to use in her stroller, bouncy seat, etc. They may have come out with something better in the past year but we used the noggin nest and it seemed to work well.
Pampers Swaddlers are great. The Pampers with "dry max", though, caused terrible diaper rash. That's really the only time my daughter ever had diaper rash and it looked like the skin was scorched. Heard similar stories from some other people...just an FYI.
Cotton onsies, comfy pj's...that's pretty much what my daughter lived in. No frilly, lacey, scratchy material at all. You'll find that's the last thing you'll want to put on your baby!
If you don't breastfeed (I did for about a week...) you may have a trying time finding a formula that works for your baby. We went through a number of formulas which caused major spitting up, horrible constipation, etc. before finding out about Nestle Good Start. It was the best for our baby. Just worked well with her system. We had no idea finding a formula would be SO tough.
I would absolutely recommend a white noise machine for the nursery. When our baby was sleeping in our room we used it in there as well. The one we have makes white noise, nighttime noise, rain, sounds of the womb, etc. We still use it now in our daughter's room and she's 16 months old. We bring it everywhere with us. Hotels, grandparent's house, etc.
Another great invention is the breathable bumper for cribs. The Pottery Barn bumper I bought was beautiful. Too bad I never used it! Again, SIDS paranoia! Breathable bumpers are not as pretty as other bumpers, but they give peace of mind since baby can't bump her head or get her limbs stuck, and if her face presses into it she can still breathe.
Hope this helps!
