What I registered for that I found out I didn't need:
Bottles. My little guy is breastfed and we never got around to using bottles. He's five months now and we're just going to go straight to the sippy cup. I would suggest not buying them if you plan to breastfeed and picking them up only if you need them or are going to suppliment.
Nipples and bottle drying rack, bottle brush, etc.
