I am with Ruth and Mom at home - I use water and I do not mind doing it at all. I have two peribottles from births and I keep one in each bathroom. My girls are both potty trained - the little one is an early bird, 21 months and about 1 accident (pee) a day, poop has been under control for months. I use the peribottle to wash dd who is almost 4 while she is sitting on the toilet and with the young one, I just pick her up from the potty and take her to the sink, facing me.
I must say I have never used wipes in the diaper days too, just water. Seems nicer to me, quicker, and, cheaper too!!
