i use a trifold hemp doubler (or 2!) in the wettest zone (for my son that's front and center) in any regular diaper, and put wool pants on top as a cover.
Another thing that is really easy for me since my son doesn't wake up if I change him, is I know that he'll pee one huge flood the first time he wakes up to nurse, so right after he nurses, since I'm half awake anyway (we cosleep), I have a new diaper/doubler set up right by the bed and I quickly (like, 20 seconds) swap the soaked diaper and put on a new one. When he wakes in the morning he floods that one, or sometimes as he's stirring and kind of waking up in the morning. I remove that as soon as we wake up in the morning, and he floods 2-3 more diapers in the A.M. and I am quick about changing. The funny thing is that after all that effort in the early morning hours and late morning hours, then in the afternoon/evening/nighttime-before-I-go-to-bed, he doesn't pee much and he doesn't pee often. So he goes dry for long stretches and then piddles, trim diaper works fine, etc.... no effort. Strange.
Any of you guys have babes who flood during half of the day's cycle and barely piddle the other half?
