We color code. Towels, hair brushes, tooth brushes. They are all color coded to our assigned color. My brother likes to shower twice a day- which is so great for a teenage boy. Yet, he likes to use a clean towel every time. I got tired of reaching for a fresh towel mid week and finding them all gone. I went to Target and bought 3 towels for each of us in our new assigned color: purple, blue, green, pink. Everyone can now use a fresh towel every time but they’re responsible for cleaning them mid week. It was a game changer. By changing the tooth brushes to the same system it worked out damn well! And yes- I caught someone using my tooth brush cause they thought it was theirs before this system went into play. So gross!
