My wife and I are thinking about redoing our floors. I would like to put hardwood floors throughout the downstairs and in the high traffic areas upstairs. I would like to continue to put hardwood treads on the stairs for the look they would provide, however, I have a baby that will be walking soon, and am worried about the hardwood treads being more slippery than the carpet that is there. Is it okay to leave the stairs carpeted, aesthetically? Thanks for the help!
