Re: What to buy for a newborn baby?
I think unless you have a lot of space, you can even do what Ira mentioned or simply add bottles to boiling hot water for a minute or 2 and then let air dry. I believe a diaper dispenser is just a cute holder for the diapers, that you can hang on the crip and easily get out diapers...and they usually come matching with crib sheet sets. (Babies r us).
I think a Diaper Disposal System is necessary. Here we have the Diaper Genie and a few other brands that let you dispose of dirty diapers in an airtight container that doesn't let out any odors.
