This thread is utter madness.
@Anon10 you're being utterly ridiculous. A sugary drink once in a blue moon, or diluted squash/OJ at home is not going to be 'detrimental' to anyones health.
I think you're projecting massively. Either that or you've got an awful relationship with food/drink (which would explain seeing sugar as tantamount to poison.)
I am underweight, with perfect teeth and I enjoy sugary drinks. My DD is a perfect weight (GP measured and weighed her not too long ago), with perfect teeth and she enjoys a sugary drink too.
It's down to self-regulation or (in the case of children) parenting.
I'm unsure of how having diabetes run in your family means that you or your children can never have something sugary - as long as none of you have the condition the odd drink isn't going to harm you.
Alcoholism runs in my family, doesn't stop me from having a drink - I can regulate myself.
Of course, if you can't trust yourself around sugar and don't feel that you'd be able to parent the consumption of your children - then I understand never having any options in.
Will wait for the post in time from you explaining how your child is being sneaky regarding sugary drinks and guzzling them down at lightening speed because they're frightened you'll catch them.
Christ alive, what a boring way to live.
