I'm not sure if I am the first person to use this hack, but it came to me today before we went on our run. I took one of my rubber bracelets (like the Livestrong ones) and put it around Fletch's sippy-cup. Then I used some of his toy rings and attached the cup to the stroller. It was within his reach the entire time and didn't get dropped on the ground or lost. I had just read that someone suggested using these to keep your cabinet doors shut also. Pretty handy little fashion statements don't you think?
