How many covers do you own (use) for your toddler? For my 2 yo ds, I have 5 xl me airflows, 1 lg. PUL sugarbums, 5 Happy Heinys (pocket pul/fleece combo) 1 lg. wool aristocrat, 1 wool cushie tushie, 1 wool first class baby and some bumkins and proraps that I really don't use.
What materials are they made out of? see above
Do the wool covers really keep moisture from wicking through (I understand the theory, but am still not fully clear on how a porous material keeps moisture from going through--I have one acrylic fleece pull on cover, and it feels damp on the outside after one use)?
Yes, my wool soakers combined w/a hemp prefold keep DS's pj's and sheets nice and dry. Some mornings I notice some wicking but everything is still dry. I'm sure a more experienced cd mama can explain the properties of wool - all I know is: it works
What about the new wool pants I'm seeing?
I have a pair that I haven't used yet.
Any thoughts would be helpful. I really like using Happy Heinys (size lg) w/a toddler cpf stuffer for ds during the daytime.
