Lily has been night dry since well before Christmas, so what's on her bum when she's sleeping is not a big stress at all, lahtough we usually stick with the night nappies or BBBs so she can do her enormous morning wee in those if mummy is too sleepy to deal with the nappy straight away or the inevitable floor puddle.
She has day naps in no nappies with no accidents.
SO last night was the ultimate test, after no day sleep again

she went to asleep early at 7pm, with a medium itti bitti on and no cover. She sleep part of the night in her bed, woke twice for a feed, and moved into our bed where she slept until this morning. Woke and had a feed this morning and the nappy came off dry

Now the day thing that's a total other story

I'll save those funny tales for another thread.
