I didn't use any on mine. The first two were girls, (in about 1966) and if their bottoms were even slightly damp when they were powdered, it clung and clogged as a paste in the creases. There were no warnings about talc being dangerous then. These days, baby powder doesn't have talc in it, nor does dusting powder for grownups.
My MiL wanted me to powder the girls (she only had boys, whose nooks and crannies are all external, and failed to understand the clogging problem) . She babysat the first baby one evening when we were out, and when we came back I noticed a pale patch on the Tintawn carpet in the hall - remember that? It was made of sisal and was very "three-dimensional" - very popular at the time. She confessed that she had changed baby on the floor, had powdered her bottom, and had dropped the tin, which left a heap of powder on and in the hessian-like surface of the carpet. To clean it up and hide the evidence she had scrubbed it with soap and water, which had combined with the talc to form a paste which made it worse.
