I have old style bamboozles, bamboozle stretch and LL size 2's as night nappies. Usually boosted with an EP hemp, a LL bamboo and the bamboo insert out of a wonderoo V2 or a pop in, under wool and they just about last Grace the night
she does BF a lot still at night though
(i have a WNNN and I still have to boost this with an EP hemp) The LL is an inch or so shorter on the rise so i'm not sure how much longer i'll be able to boost so much inside the nappy, although the elastic seems to be stretchier so maybe it'll be ok........ I also find that the LL is squashier and softer material. I hope they work out for you
