I agree, cotton in the early days works well. We had cotton TB & Terries with Scarlett and they were fine, quick drying and as someone else said, you can easily boost (with bamboo if you want) to make them last longer if baby is a heavy wetter.
I liked the quick drying time. Could have them washed & dried over night ready for use again the next day. Ideal for DH when he was taking the nappies home to wash when i was in hosp.
I have Sandies this time as my 'cheap quick drying' ones - My 'spares' as i like to call them, also ideal if just before bed or out of the bath etc so its not a big deal if they get pooped on. Would hate to have to wash and dry a bamboo or WAHM one for the sake of 10mins on their tush lol.
