I'm also expecting a large baby, so haven't gone overboard on tiny sizes. With Iris (who was in cloth from when we got out of hospital, on day 6), I had just 25 nappies. Plus 10 muslin squares that I never used as nappies, as I'm useless at folding flats. It was enough to get by with washing every other day. I did take cloth to the hospital with Iris, as they were happy for me to do so.
But we didn't use it due to her being in SCBU and me having more important things to worry about. We'll be taking cloth to the birth centre this time.
So far, Bean has:
6 xs Sandy's - just in case he is a tiddler!
4 small Wee Notions Northern Lights
2 medium Itti Bitti AIO (I find these tiny, hence the mediums!)
2 small Dunk N Fluff
2 small made by me (Darling Diapers - same pattern as a Dunk N Fluff)
1 small WN SS
1 small Pocketbots
2 Baby Beehinds OS
1 BubuBébé OS
3 Piddle Poddle OS
3 Easyfit OS
1 Little Britiches OS
1 Cushie Tushies OS
Oh, and I also have a small Bumhugger and a medium Flutterby Fluff night nappy for him - ready for once he's a bit bigger and in to night nappies.
Then I have 4 small and 1 newborn soaker, with another two small soakers expected from Sadie soon. I won't buy/knit more until he's in larger sizes; I don't need too many small ones as they will dry very quickly here in summer. And 1 small Blueberry wrap. Oh, and I have a medium WN wrap to use over night nappies, too. I have a ton of interlock, so I should knock some boardies or soakers together for him (been meaning to for ages!), just 'cause I can.
I also have enough fabric to make a further 6 nappies using the Darling Diapers pattern. I think 5 of those I'll make as mediums and 1 will be a small, as I have an embroidered tshirt for Iris to match the nappy cut for Bean. They can wear them for the official photos to send the folks at home.
I don't know yet whether to buy/make a few more small nappies or wait and see how big he is and what shape he is and buy more when he's born. I'm leaning towards the latter, TBH, as I don't see the point in having a ton of stuff that might not work for him. I do have a million hemp pocket inserts that I could use as prefolds if I get really stuck while waiting for new fluff.
But I expect to wash every other day and not have to tumble this time, either! There is one small bonus of having a baby in the heat we'll have in January.
