good thing you are planning on breastfeeding.... but you should buy one can nonetheless, just in case...

I too bought a convertible crib that could be turned into a toddler bed and after that we bought big kid bed the normal individual ones even grown ups use...

oh oh... get a matress cover... just in case you get spills (pee/poop/milk,etc) so it doesn´t gets ruined...

there are also lots of stuff... most of it unneccesary... but you´ll figure out and prioritize the needs vs. the wants......

are you having a baby shower?... perhaps you can ask for gift certificates as presents... I would say diapers but you need to figure out which works best for you and your baby so you don´t end up with tons of useless diapers...

oh and DO NOT buy tons of baby clothes... they´ll leave it behind in DAYS.. literally....if you really really like something, buy it the next size up so it gets weared at least a couple months... same with shoes
