At 3.9, ds announced he no longer needed any kind of nappy at night. There would be no wees in the night and if there were, he would do them in his potty.
Well, ds may have thought he was ready to go through the night dry, but he wasn't, and, many washing cycles later, I succumbed to the advice of dp, my mother, my m-i-l et al, and began lifting him at night.
And this is where we are, five months later. One of us has be awake between 11.00pm and midnight to lift him in his sleep to use the potty - trial and error has taught us that this is the timeframe that can guarantee a dry night.
If staying dry through the night is a muscle thing that develops, or hormonal thing that kicks in (I don't know what it is but I'm sure someone here will), the ds doesn't have it and I can't see how this night-time lifting will help him develop it.
So how do we stop? Do we go cold turkey and endure a lot of wet beds again? TBH, I'd put him back in pull-ups like a shot but ds point-blank refuses to countenance them and gets terribly upset at the very idea (he thinks he's dry at night, after all).
