My entire family was sick last week (me, my husband and our 16 month-old son) so there were countless medicines to keep up with. I kept track of the different medicines and the times they were last taken by writing a huge note directly onto our bathroom mirror with a dry erase marker. You can’t miss it when you walk into the bathroom and it easily wipes off with a tissue or the hand towel – you don’t even need Windex. Now I keep a marker in the bathroom all the time (for those little revelations you have in the shower) – when we’re not sick I write myself little reminders: “pick up diaper cream” etc.
Seems like an ideal way to communicate with a teenager as well.
