|I had read other moms on the forum mentioning that you didn't need to dry in between washes, so I did the three washes in a row. I used detergent in the first two washes and nothing in the third to make sure diapers were rinsed properly (as I didn't do an extra rinse). It worked fine for me, although I had a newborn so as PP said, you don't need much absorbency at that stage. When I received new diapers later on, I pre-washed the same way, but the first few times they were used we did notice they were a bit less absorbent than our old ones. They still worked fine, though.
A side note about lint: ME mentions not to wash more than a certain number of diapers at a time for fear of lint accumulations. I found that it depends a lot on the fabric. People have mentioned lots of lint with the cotton diapers, but when I pre-washed my bamboo diapers there was barely any lint on any of those three washes, so I could have washed more than the amount mentioned.
