When my baby son was in nappies, my wife tried everything she could to rid the little mite, of a worsening nappy rash. She tried every lotion, powder and gel on the market, to no avail. Even a prescription from our local GP failed to clear the problem up.
Then one day, the health visitor called and took one look at the nappy rash and exclaimed, “Cover his bottom with plain old powered starch, my dear, it'll soon clear up”. She did and the rash had gone in two days.
Three cheers for rash advice.
