Has anyone got a solution for leaky nappies with side sleepers? Ds is 5, still has a lot to drink in the evening and overnight (fortified milk for weight issues). Sometimes he wakes for the potty, sometimes he sleeps on through as the enormous pee leaks through his nappy, clothes, soaks the bedding. We're stuck with pull ups because he does wake and go independently often. I've sized up to the teen dry nights from normal size 8 pull ups but they don't work either. He's very tall and skinny, but this isn't a gap issue (with the size 8s at least). The size down is definitely too small. Any ideas beyond those washable bed pads?
