Fitted - I love swaddlebees OV newborn for the fit and containment but they really wont fit William for much longer. He was 9pound 4 and they only do up on the last poppers (and it was the first nappy he wore) so maybe a small would be better - we got ours on ebay. The natty napnaps AIO we got from our secret santa (Rae) is great to and has lots of growing room even though they look really tiny.
Pockets - Swaddlebee pockets are great to if you want to try pockets we have a medium and it fits him surprisingly. Green kids are good to folded down abit.
One size nappies - Bubba J Hemp (they do a bamboo aswell) are really good they fold small and are great for containment too. Ecobaby's are alright but leak if its a huge poo
I have lots of WAHM nappies for William and havent really found any I dont like. If your expecting a big bubba I wouldn't go for many nb size at all.
