I use prefolds in pockets almost exclusively (in fact, I sold off most of our MF inserts because I never used them). Currently, we use our NB prefolds tri-folded and stuffed in our pockets. As DS grows, I'm sure we'll upgrade to larger prefolds (he's still wearing size small pockets), but for now, these work great!
Yup. I use prefolds in my Alvas all the time. I also use 2 prefolds stuffed in them as my overnight option. Super bulky but it never leaks no matter how much she rolls.
Yes. I am short on covers now and really preferring prefolds. I am just tri-folding them so that the natural fibre is against her skin and then if it is only damp I may re-use it. I need to buy some more proper covers I guess, but money is a little tight now and I have the pocket covers...
