we've got an bumgenius, small AIO on her now, with a nice big bit of muslin under her to catch any leakage, will see what happens, if it leaks i will try the motherease aio (im finding the less good looking nappies do the job better lol) then will try a bumgenius pocket.
i think they (swaddlebees aio and pockets, bumgenius aio) leaked before as she was too little but strangely it leaked out the top, i cant remember if it was loose at the top before, its not now but obviously with movement there is normally a gap anyway so cant see why that would have been why
