Gaaah! I should never have peeked there. oh my gosh, those new colors are awesome! turqoise, orange, grape and brown, tangerine cream and of course that orchid color (which thankfully is not available in the small.) I would love a fuzeasy or fuzbomb in one of each. How pretty that would be.
Enough gushing, let's see if I can answer some ?. I have a small fuzeasy in the Marigold for my new babe and it's so soft and beautiful. I probably would not use one as an overnight cover on my toddler, but for my babe, who still has several changes a night, yes, it works just fine. It really depends on the absorbency of the diaper underneath to a large extent. I sometimes wash mine in the front loader (no agitator) on hand wash cycle, but I wouldn't put it in a washer with an agitator, though it might be fine. Can't help you much with that, sorry.
They are pretty trim under clothes (depending ont the dipe of course) and they go over pretty much any diaper.
Deciding between the medium/ large - hmm, you could always go by the fuz chart and then add some extra snaps at the waist and legs to get a higher rise for a slimmer child. I have done that and it works great.
Kristin, hope your house sells soon! It's always so stressful.
