Having got my children to drink more water, I used to buy bottle water so they would think it's cool to do so. Now wanting to lessen our carbon footprint decided to to go with reusable water bottles. I thought I would be going through many reusable water bottles. I was wrong. I am still on the first bottle I got them. My son who has autism manages to remember to bring his bottle back at the end of each school day. In a way it also have thought him to be a bit more responsible for his things. As for my daughter, she also remembers to bring her bottle home with her. I have to say I am very surprised they have become responsible of their belongings. In my books that is a good thing.
