Many of you have probably done this when your kids were toddlers - water down the juice. Well you can just keep on doing it. Most juices like Juicy Juice, Sunny D, Hawaiian punch, etc. are just too sweet to begin with. I fill half to 2/3 with juice and then just add water. My kids 8 and 5 have never complained or known the difference and it extends the life of a bottle of juice by a lot and saves your kids teeth too.
