This was prompted by a thread that I've just read but it truly honestly isn't meant as a dig at the OP - I understand that it wasn't just the choccy under discussion in that thread.
No one wants their kid eating sweets 24/7 but honestly, is it really so bad every so often? Forbidding something always makes it more attractive and I can see a generation of serious chocaholics descending on us in a few years. Aren't there far worse things to eat? And where has all the fun in life gone?
Ban this, don't eat that. It all seems very miserable to me.
