anemone: i couldnt have lived without my BFing pillow. If you can live without it will probably depend on your physical charasteristics and those of your baby (how long your torso is, how big your (.)(.)'s are, how big your baby is etc). Also probably a great deal on where you plan to feed. I was using a chair that had no arms most of the time so had a cheapy (from Target) BFing pillow that wrapped around my waist and attached with velcro. I used normal pillows in the hospital and when at mothers group no pillows and I found both of those situations really hard and frustrating to feed in.
As for not using wipes - ive heard of people using olive oil with large cotton balls for changing dirty nappies. I don't think I'd be using soap as it dries the skin out - more of a moisturizer (so a lotion). Also if i were you I'd like into QV as Aveeno is actually made by J&J so not sure just now free of any nasties it is. We use the QV lotion here for massaging ds and use the body wash for in his bath (had bought organic stuff but it gave him a rash).
