Ilovemydog! HOW MANY TIMES DO I HAVE TO SAY IT??? Reliable night nappy? Baby Beehinds bamboo (or hemp if you are Isaidno).
I know some people complain they come up small on a toddler but DS2 is a fairly average-size 2.7 and I think they should last till he doesn't need them any more.
They are BTP, lovely, lovely, lovely, and I have never had a leak with one and a fleecey Stacinator.
Baby Beehinds come with two snap-in boosters - I use both with DS2. I used to use extra boosters because previous experience made me paranoid, but I soon realised that I don't need to.
They are quite fleecy naturally so I don't bother with a fleece liner - don't really like putting artificial fibres next to his bum, he goes a bit pink at the edges.
Before that I tried Fluffles with extra boosters (enormous, smelly, and leaked) Bumhuggers with extra boosters (effective but I prefer Baby Beehinds), Bamboozles with extra boosters (feel quite clammy when wet and I really would rather not use fleece liners to keep him dry)...
Then of course there are utterly gorgeous night nappies like Holdens Landing Bedbugs which I look at and drool over but could never justify as they cost over $30 plus $6 shipping and almost never come up second hand and when they do they are gone in seconds...
