I have washed all my reusables once but mine are not terry. They say that they are not at there ful absorbancy until they have been washed 3 times, so as long as you know this then I'd just chuck them through the wash once, dry and use them. Im sure by the end of a week they will have been washed three times anyways! I just added a tiny bit of fairy non bio to mine.

edditted: just seen that youve not had bubbs yet, so yes I would wash them 3 times, do it over a week or so and let them dry on the line in between. This way they will be ready for the new bubba. Newborns wet loads so you would benefit from them being at there full absorbancy. Why did you go with terry hun?
