Like "The magic number is like a magic pill...there is not one that works for everyone. Kids have to be especially though and I admire parents who are brave enough to allow your kids to take care of themselves. Oversight is always there, but rebellion can have really bad results too. I know how difficult it is as an adult to get that number that is healthful, I can't imagine watching your child go thru lows to try to achieve a good A1c...It's like the kids that don't eat to achieve that "vogue" look. I suppose we have to be careful of the pressure we put on our kids to achieve that "magic" number."
