I've just replied to you in today's chat about the huggle.
Have you tried the bamboozle with wool? It does seem like the huggle might be the problem not the wool, as wool works even better than fleece generally.
Have you tried the huggle with the fleece wrap?
Anyway, other great night nappies are Weenotions Night Notions, Puddlepants weedies, baby Bufters night nappies, Hollow Oak and Jimmy Riddles. Or you could try a minki pocket as they are fab for night.
