We did not use our fireplace last year. We thought it would just be too much of a hazard with the twins. DH & I were talking about it over lunch, whether or not we would start a fire this year?? I still don't know about..... We don't have a glass door or cover. It is just one of those mesh screens. For those who have fireplaces, did you stop using them when your kids were younger? What age did you deem it safe for use?
