Re: Overnight leaking
Lanolized wool soaks up and holds liquids before it leaks, so it just feels a bit moist. Doesn't seem to bother LO at all. You need a very absorbent diaper underneath. Don't count on the wool as part of your absorbency, it's just there for extra security.
In the morning you just let the wool air out and then you're ready to go. It only needs to be washed every few weeks, or when it gets dirty or starts to smell.
Sounds like part of your problem is that you need more absorbency in your night time diap. Have you tried bamboo or hemp?
