I am nearly CERTAIN this has been asked before, but my search couldn't find exactly what I was looking for. I apologize in advance.

I finally did a count of what I have from a friend and outfits from my MIL. I know the whole "three outfits a day" thing, but I wasn't sure what applies to the below things. And from what I've read, Sleep 'n Plays are golden when the baby's little, so these things are the only "clothing" items on my registry, and I don't want to even have them on there if I already have enough. What are your thoughts on the quantities I have below?
Sleep 'n Plays:
NB: 1
0-3 mo: 1
3 mo: 2
3-6 mo: 6
6 mo: 2
6-9 mo: 3
9 mo: 4
Sleep sacks:
0-9 mo: 4
SwaddleMes: 2
Re: STMs (and beyond): How Many Sleep 'n Plays/Sleep Sacks?
Four sleep sacks + 3 swaddles seems like a lot. I would say 1-2 sleep sacks are enough if you want to return some of the ones you have.
Also, I wouldn't register for any clothes - you will get a ton anyway.

I have about 20 NB sleep n plays because that's all DS wore and he was teeny and in NB size from his birth in October through at least Christmas. I'm sure we won't need all of them for this LO, but DS wore every one! His 0-3 stuff is spring. :P So that's what we've had to buy in wintry clothes.

I had 2 swaddlers with my boys. It was fine, but more than a few times one would get dirty before the other one was washed/dryed. I bought 2 more for this LO just to make it easier. Your baby might not even like being swaddled so 2 might be good until LO is here, then you can go buy more if necessary.
