How to Lanolize a Wool Diaper

What you need:
Baby shampoo (or wool wash)
I primarily use wool diaper covers at night on Charis.  Why did I choose this?  For a few reasons:

Wool is water resistant.  Lanolin is what makes the a sheep's coating waterproof and makes wool covers "waterproof".  Wool absorbs water, absorbs up to 30% of it's weight without feeling wet.

Wool is breathable. Breathability in diaper covers is important for a baby's skin.  If the skin can't breath, then when a diaper is wet, the temperature rises, and can cause a diaper wash.  During the day, I use PUL covers (but I change Charis QUICKLY when I realize she's dirty), but at night she's often in her diaper for 12+ hours.

Wool can go a few weeks (3-4) without washing.  Wool is naturally antibacterial and should not smell like pee when dry but if it does then it's time to wash and lanolize.

Soaker lanolizing in the solution
How to lanolize a wool diaper:
  1. Squirt baby shampoo and place approximately 1 inch of Lanolin into a plugged sink or basin.
  2. Pour boiling water over the shampoo and Lanolin.
  3. Stir with a spoon until the lanolin dissolves.
  4. Turn on the tap and run lukewarm water into the sink.
  5. Place cover inside out into the water and swish it around a tiny bit.  Warning: make sure the water is not too cold or too hot. You do NOT want to shock the wool or cause it to shrink too much.
  6. Let it soak for 30-60 minutes.
  7. Remove from water, place between two towels, and roll the towels up to help squeeze out the water.
  8. Let dry for about 24 hours.  
Do you cloth diaper?  If so, what are your night time solutions?  
Have you ever tried wool? 


  1. Our night time routine has always included a BumGenius pocket diaper. We use yellow to designate night time because it is usually double stuffed. We no longer use the microfiber inserts but rather flat cotton diapers inside the pocket. Works great and no longer have sink.

    We do use wool. Mostly shorties or longies I've made both from old sweaters or I've knitted some. I have lanolized them. I did it once in the sink. Now I use a bowl - I did not like the oil deposits left around my sink. And I boil the water then stir in the lanolin. Then I pour it over the wool item that is soaking in lukewarm water. It works for me. So very similar to what you do but just a bit different.

    By the way, you asked about the dress my daughter was wearing - yes, a pillow case dress but I just found some clearance fabric - about half a yard and made it from that. Then I sewed lace on the bottom. The project took less than 2 hours.
