I don't use gloves when changing bums pee or poop and never have - 25 years of daycare and 4 of my own. I just wash with soap and water between - don't even use the purell like some do because I don't like it and not totally sure I believe in it. I do have a box of gloves and will use them if I have to put a special cream on a child with a rash/yeast infection but for routinely using creams no just do it - or I will use a piece of toilet paper to actually swipe it on which spreads it around really well and keeps the cream off my hands which can be hard to wash off which is the idea behind it.

Funny that poop never bothers me but anything beyond a baby spitting up and I have a hard time with that one.
