I think with my first about a week, i got so fed up of fetching water everytime and cotton wool just doesnt shift poo like wipes do. The only ones we dont use are johnsons as they give my son really bad nappy rash. The cheap ones from Asdas and Tescos though we have had no problems at all. In the beginning I only used wipes on his bottom, the whole cleaning face and other areas I still used water with either cotton wool or a flannel for a good while.
