I'm really interested in people's experiences with cotton/wool crib mattresses. We are debating buying one from Organic Grace, but I've read that mold can be a concern in mattresses without waterproof coatings. Since this is our first child, I really have no idea how likely it is that the mattress will get wet enough to develop mold. We would use a wool pad between the sheet and mattress to help absorb any moisture, but would this work well enough?
We are also considering the Naturepedic organic mattress, but I'm really not wild about the plastic surface, even if it is supposedly non-toxic.
