Hey Lisa,
I used the shower head to spray during my recovery and only used regular cotton balls that I wet w/ warm water. If you have to use baby wipes then I would get the dye free, perfume free- hypoallergenic. I have ran warm water on the wipes and rinsed them out before using them. I would put some cotton in a ziploc and some baby wipes and find a handicap stall with a sink to use to clean up if I were you. You definitely want to dab and not wipe to hard I'm sure you already know that, though!
It's too bad you have to go back to school so soon during your recovery... Setting on your butt this soon and moving around so much probably isn't going to speed the healing process up...
