Just that really. I'm thinking about getting some for DC2, on the way, but didn't use cloth nappies until DS1 was 6 months old so I never got the small size. I have SIOs in medium and large, but was thinking of getting AIOs for a newborn for convenience.
We'll be having a winter baby though, so I was wondering if you can stick them in the tumble-dryer to finish them off? I often did this with the inserts of the SIOs, but not the outer shell. TIA :)
