DH put Emi in a WNOS last night, normally she's in disp. for the night and this morning I found her without any leak. She was in it for 14 hours I'm totally flabbergasted Oh and it was stuffed with one, yes only one, bb insert.
I've just started using these too, success with Ecobubs convinced me that other pockets would probably be fine for nights (DD isn't a heavy wetter)... no problems! I use two EP hemp and a bamboo booster on top.
