The only other thing I just thought is that as she has only been a light wetter til now alot of your nappies are fine for that and not for heavy, ie cotton pul covered pockets etc. Maybe just try using only things that are better for heavier wetters if that makes sense! Sorry just thinking what else to suggest.
In my somewhat limited experience with bamboo (could get them out the drawer to try again ) don't the bamboozles absorb around the same amount as normal cotton tots type nappies, just the bam is slimmer. Sounds like a few extra layers of boosting might be needed even in the daytime.
I think I found a good combo especially for night time - a tots original or bamboozles and under the flap a bamboo BBH fold up with a flannel wrapped around and a mf booster on top and then a fleece liner on top of the flap bit. I really do need to get some more proper night time nappies though
When my fllece lined night nappies are dirty/wet I use my bb bamboo, with both its boosters and you can slip a mf cloth/ bit of hemp what ever in to boost plus a fleece liner on top and it works a treat!
