For what it’s worth, to help keep your cold from spreading around the house, if you’ll mix up a 50/50 mix of Peroxide and Vinegar that’s what they use in Bio-chem labs that handle things like salmonella and small pox. To that, in my birthing center, I add 20 drops of tea tree oil to a 1 quart bottle. While it may not smell like Roses or Lemons, it kills all the harmful bacteria, and doesn’t breed super bugs like a lot of the “anti bacterial” cleaners can. Besides that, it actually kills the cold virus which most commercial cleaners fail miserably at.
Just mho, fwiw.
P.S. The fumes from this are minimal and everything is non-toxic, so there’s no worrying about your little one with this.
