Has anybody tried wool boosters? I contacted Emma at Puddlekins for advice about night nappies (she's amazingly helpful and knowledgable btw, she's like a nappy scientist!) and she said that she'll make our next order more absorbant and suggested that we try wool boosters in the Puddlekins NN we have already. I thought it sounded odd at first, but apparently wool boosters go underneath your normal booster and they kind of force any moisture into the absorbant parts of the nappy, then once that's full the wool also absorbs quite a lot. It sounds good in theory but has anybody tried them? We use wool pants and we love them so I'm hoping the boosters will be another thing we love!
