Here's how I manage whose water bottle is whose in the fridge:
I put all our names on those big rubber bands that come with broccoli or asparagus, and stretch them over each person's bottle. These are also no big deal if they get lost or thrown away, since they're free. If you use a Sharpie marker, then they' re also very washable.
The best way to write on them is to stretch them over an empty water bottle ( a full one is wet and the marker doesn't work well on a cold, wet, bottle) Then write the name, and pull it off and store them in a drawer or something. My kids never remember to put their names on their own bottle, but it's no biggie for me to label them. You can see that I'm almost done drinking my water for the day... ( pat myself on the back, pat,pat)
Now I can say with all honesty that my whole family are big water drinkers. Our fridge is not complete without a load of ice cold water bottles ready to grab and go. Summer or winter, we all love drinking cold water!

What great ideas! Love the free-rubberband "labels"
