When Hannah was a baby and in cloth, I was having trouble with her waking up when she would wet. Somehow I got the idea to make fleece inserts to keep the wetness away from her skin when she was sleeping.
I went and picked up some fleece and cut it into rectangles, just big enough to cover the diaper when folded. When she would sleep, I would put one of these on top of her folded diaper. They worked great! She would stir a bit when she wet, but would soon fall back asleep. I continued to use them as she grew, but I used different colors of fleece for the different sizes, making them easier to sort.
Now that Isaac is in cloth, I have pulled out the fleece as well. It does add a tiny bit of bulk, but it's definitely worth it for naps!
(I scheduled this post before our washer went out, so maybe now I will have to also post my disposable diaper trick.)
