My DD is 18 months and I've been using these all of her little life. It makes washing her a little easier. I keep some in the kitchen too for when she is done playing outside or before she eats. I lather her little hands with them and then rinse her under the water. Because the box can be a bit bulky if packing them for a trip, I keep some in a plastic baggy in her diaper bag for those times. I've seen them almost everywhere - WalMart, Target, grocery stores.
