Nope, not just used for babies to prevent diaper rash.  This is something that you can find in the bathroom under the sink in a black household and most likely there might not even be any children in the home.  Baby power is a ritually used product, that is placed on the body to absorb sweat after taking a shower/bath.  The term “so fresh and so clean-clean” is usually topped off, with Baby Powder being placed on the body, usually the chest and back area, but in some cases are placed in underwear as well, for that added freshness.  It also makes the skin soft.
