Will try again soon but reluctant to purchase yet another nappy as she wets so heavily overnight that I'm not convinced that anything will work for her
Kayleigh outwets disposables, and we always end up with wet pj's with sposies (even the magic 12 hour ones).
A standard minki sells relatively cheaply, then you just need to stuff it. We have used the happy heiny hemp stuffins + 1 or 2 ellas house hemp inserts and a microfibre insert on top. It is huge, but always contains well, even our old standard minki that I swapped for another nappy and I figure had seen many years use previous to us getting it.
We also have night notions, but need to put an extra hemp booster (easy peasy) in there as well. We cover that with wool which allows some evaporation.
