Those diaper covers are magic! Made from merino wool interlock, they are  both soft, breathable...and very odor-resistant! Lanolinize a wool diaper cover, let it dry, then stick it on the baby.  It should probably stay dry through a couple diaper changes. As soon as it starts to feel damp, replace it and let it dry. You should not have to wash it at this point! It will not smell. Just rotate diapers. Depending on the baby, many people find that they can go 2-3 weeks before washing the wool cover! Unicorn Power Scour or Beyond Clean are great choices for washing diapers. You'll want to re-lanolinize after washing the diapers. ❤️🌍♻️
