I think you are all being mightily unfair to OP. She is looking at the bigger picture, and she is right to do so.
I run playgroups and only offer plain biscuits, raisins and water. The children don't expect anything else from me and are happy. I have many parents who request no additional sugar, and this is a happy balance for all of us.
At Easter I offer them a small chocolate bunny and at Christmas I make them a small
Gingerbread man and offer clementines.
And as for older kids, we lead by example. We don't eat much sugar because we just dont like it. During holidays the kids have an ice cream a day. We have fruit in the house but no yoghurts/sweets etc. If we want cake/biscuits, we bake them and rarely ice them outside of birthdays. They certainly aren't forbidden but they definitely aren't consumed daily or even weekly sometimes.
Yesterday on a school trip my 9 year old's teacher told me that he bought sweets, as did all of his mates and after he tasted them, put them in the bin except one lollipop because he said they tasted like shit. And at parties, this was my DD's spread from her birthday this weekend. All home made, the only processed sugar was the chocolate and sprinkles on the strawberries. The kids LOVED it.
OP, I think you sound sensible. Ignore all the name callers, you don't need approval from anyone.
