When these first arrived I didn't believe they would actually do anything. They're really very slim, as the name suggests, and very floppy. They're quite difficult to stuff in a pocket nappy because they're so floppy unless they're folded over or in between two firmer inserts.
I've been using them in between the two bamboo mix inserts that come with a baba and boo nappy, folded in half, which gives me four extra layers of bamboo where I need it - at the front (boy fold). You can't really tell there's an extra booster in there because they're so slim. I can see how this would be very useful on smaller babies, on the lower rise setting or where two main boosters is too much but one is not enough.
The fabric used is the same as the bamboo layers on the baba and boo mix inserts and they are the same size. It's much more silky to the touch than Little Lambs boosters and much slimmer. I can't compare absorbency between the two as I haven't done a scientific test and will let someone else do that (lol).
I live in a hard water area which has stiffened the fibres a little. But actually, this has made it feel a little more substantial, although still very floppy.
I really like these for providing extra absorbency without affecting the nappy fit. I was struggling with trying to get three boosters into a pocket without the fit being affected and these have done the job.
Baba and Boo have really listened to their customers in creating this booster.

I bought these thinking they would be much thicker (and just slimmer in width) but actually they are really thin and absorb very little, so entirely unsuitable for our 6 month old baby. Unfortunately I didn’t work this out before washing them otherwise I would have returned them.

As much as I love Baba + Boo, I was really hoping I'd like these more than I do! They provide a nice absorbency boost, but I don't like putting boosters outside of nappy pockets (our daytime stash is all pockets), and due to how thin these are, they're extremely fiddly to get into a pocket. This is only personal preference though, the quality of the product is great.
