My main one that comes to mind is soft drink too. DD is 2 1/2 and has only ever had a few sips of mine (when i have rarely had one). She only drinks water and a cup of toddler forula with her afternoon snack, but i will let her have a happy meal with nuggets (with water for the drink) if we are out and about.

When we go grocery shopping i have a strict no junk rule, i dont buy anything like chips or lollies or softdrink. But if we are in the service station I will usually get us a chocolate to share.
