My DD is younger than your LO, but we use Bumhuggers, Swaddlebees OVOS, Baby Beehinds bamboo fleece OS and a Holden's Landing BedBug at night. The Bedbug is easily the prettiest nappy of our night stash, but I think I actually prefer the Bumhuggers of them all; they're fleece lined, so keep her nice and dry overnight. Iris can be a heavy wetter, so the new style EH's are perfect for her, as they can be stuffed with an Easy Peasy hemp to make a really absorbent nappy.
I've yet to take the plunge into wool at night (I'm scared!
Once I've lanolised Iris' longies once more, I will try her in them overnight), but we use wool during the day. It's surprisingly easy to care for - just wash with olive soap, either towel roll or spin on a low setting in the washer to dry and lanolise as and when.Just air dry between uses to make sure your soaker/shorties/longies don't get too honky. The Pure Wool section has lots of info about caring for wool.
