Playtex Diaper Genie Elite Diaper Disposal Pail. If you do disposable diapers, this is good to have to keep the diaper stink to a minimum :) Its worth the extra couple of bucks to get the elite with the foot pedal.
Huggies Disposable Changing Pads - 8 pads/ Pack, 5 Packs. We only have one cover for our changing pad, and we keep a disposable on top of that. They last for weeks and weeks but it is good protection in case of any on-table accidents. Also, in those early days when you still are struggling with HOW to change a diaper, it nice to scoop up the whole mess in one of these.
Pampers Swaddlers. We use disposable diapers. These have been great. We've only had leaks a handful of times and it was usually because we needed to move to the next size up. Only buy one box of newborn size - we moved to size 1's pretty quickly. These also have a blue strip on them that indicates when they are wet...Eric loves this feature. A couple of times we used other diapers without it and he always complained about it :)
