Years ago I became grossed out by the idea of keeping toothbrushes out on the counter in the bathroom. To me that's like eating a sandwich that sat out exposed in a bathroom while one person after another pooped and flushed and peed and flushed and spashed germy water all over the place. I wouldn't eat that sandwich, and I wouldn't let my kids do it either.
Anyway, because I'm weird about that, in the old house we kept our toothbrushes in the medicine cabinet, but now we have drawers the right size for cutlery trays.
There's space for toothbrushes, toothpaste, and "kissy-face" (Chapstick) for the kids to access easily.
I used the same kind of tray for Sophie's hair accessories. So simple!
